I am an American, and travel often, so I do not hold our Airbnb European stays to "American standards". Maxime met us at the apartment, gave us the tour, answered questions, and was very gracious. He was responsive to all questions via Airbnb app.
The apartment is what Americans would consider on the 5th floor, although the address says 3rd floor:
Ground floor (E), then 0, 1, 2 & 3; with 2 or 3 more floors above.
We were there in March 2022, and there was extensive renovation work being done in the small lobby. Not an issue, really. Marble walls and floors should look good in the future. Small elevator rated 300 kilos max (660 pounds - 3 people with carry-ons). Long haul by stairs; elevator is fast enough.
The apartment is large by European urban standards: 3 bedrooms; 1 with complete shower & toilet (end of the hall), 1 with tub/shower & toilet (end of hall), and 1 with shower in room and the toilet & sink off the hallway nearby serving as a guest toilet as well (just past the front entry). My preference was the tub/shower room at the end of the hall to the left. Sleeper sofa in living room. Plenty of closet and storage space.
The rooms with the toilets were unique in our experience. They were adequate size and modern. A step up to get in from the bedroom (beneath which the plumbing was installed as a retrofit. Back in the day, it was common for apartment tenants to share bathrooms on each floor.) Here's the real rub: there is no door into the baths & toilets; a curtain separates the sleeping area from the "business" area. My wife and I developed a code, "I need some privacy for a little while", as we headed down the hall tiward our room. Big windows allow immediate and effective ventilation. There are these weird sliding opaque glass doors that slide, in turn, to obscure either the sink or the toilet. Couldn't figure out why they're there, because when closed, one cannot fit their legs between the glass door and the front of the toilet. Plenty of hot water.
The large windows to the bath have a louvered shade outside, but by no means provide appropriate privacy from the hundreds of windows with neighbors in the surrounding apartments. The bathroom lights are bright. We ended up shutting off the lights in the bathroom, and let the filtered light from the bedroom illuminate the bathroom through the curtains. It was not ideal, but effective.
There is a clothes washer in the large closet in the kitchen, but no dryer. There is a drying rack stored next to the washer, with small space heaters to help with drying. There are clothes lines out each bath window. Clothes pins present in apartment. There may or may not be detergent present. We bought more detergent at the convenience store across the street. Jeans take a full day (if not more) to dry.
The kitchen has everything one needs to prepare meals. During 2 rain days, it leaked like crazy behind the stove vent hood, and spread all over the stove, counter, and floor. We mopped it up the first day, thinking we spilled water (rained during the night). As we were leaving the apartment on our final day, it was pouring rain, and we saw the active leaks with water everywhere as previously described. We put pots under drips, notified Maxime, and hauled tail to the airport. No time to mop.
If you like American-style drip coffee, there is a drip coffee-maker. There may or may not be filters or coffee. I recommend bringing both (if you have check-in baggage). Again, the store is there to bail you out. There is a small breafast table in the kitchen.
The living/dining room is adequate size, with a large dining table and 6 chairs. A modern, big-screen TV (not smart), with Spanish programming (1 station of English-language History-Channel-type programming: "HOW ITS MADE", "MT ST HELENS ERUPTION", etc. We brought a laptop and HDMI table for movies & other streaming. We're not gamers, but could have if we brought a console. We were so busy morning thru night, we didn't watch a single movie. Barcelona is a great walking city!
There are two windows in the living room which open up to balconies. They are very narrow, and not very welcoming, but on a sunny day, wouldn't be so bad with coffee looking down onto the street, or at your neighbors in the apartments across the narrow street.
Aside from the leaky kichen, there were a few ants in the bedroom with the tub. The entire place could use a minor facelift by fixing all the dings on the walls and floors, and a coat of paint. It presented as very clean. More towels would have been nice, as they take awhile to dry. Overall, it was a good place to which to come "home". Remember to bring 110v-220v adaptors for your electronics: ebay & Amazon.
The apartment sits just off the Via Gran Catalunya. There are TONS of restaurants, cafes, & clubs in this neighborhood; all very affordable and gay-friendly. The street below can be a bit noisy, but not overwhelmingly so, with both people and traffic. We walked everywhere: beaches, museums, sights, La Rambla (over-rated). There are 2 large, unique malls within walking distance as well. Taxis are cheap and EVERYWHERE; so that you'd pay less and be more efficient over taking the Metro. Less than €40 to airport. Hail one with a green light on, and they'll pull right over. Some of the larger ones can seat 6...just be a bit patient.
Remember, Southern Europeans are generally a nocturnal people. To many of us, that is a good thing: walk a lot during the day, go home and nap in the afternoon, then arise and freshen up for dinner and whatever else awaits. People will be returning home at all hours
