The apartment is exactly as pictured, extremely clean and was spacious for our family of four. Communication with our host prior to our stay was timely and informative. We arrived at 7:30 am on a Sunday so we took the AeroBus to Plaza Cataluna and stored our luggage at Barcelona Lockers which happens to be near the apartment. Another storage locker place near the apartment can be reserved through the Stasher app. We contacted our host at about 9 am to coordinate the receipt of the keys and they informed us that they would be able to give us access to the apartment two hours prior to check-in at no extra cost. We appreciated their generosity since we were all very jet lagged.
Tania greeted us on time with the keys , showed us around the apartment and provided information on how to use the appliances. We arrived on a Sunday and already knew about the extra fee (see "House Rules" section for information). Our host informed us about it as well at the time of booking, so no surprises. Our host messaged us the next day to make sure all was well with the apartment which was a nice personal touch.
The location is very central and safe to stay in. You can walk to the many restaurants, bars, stores and landmarks (i.e. Casa Batllo, Casa Mila, etc.). You can walk, take the metro, bus or taxi to any location because they are all near the apartment.
We stayed 7 nights at the apartment and it had everything we needed. We mostly ate out and had breakfast at the apartment on a few of the mornings. There is a small market across the street and a bigger market around the corner (Mercadona) for any groceries or minor items you may have forgotten.
I would definitely stay in this apartment again and recommend it to family and friends.
