The apartment is in the best location one can hope for in Barcelona. Right next to Placa Catalunya, La Ramblas (the city's main shopping streets). Easy walking distance to the Gothic Quarters, Gaudí’s Casa Batlló, the Metro and bus stops. The neighborhood has lots of tapas bars, Ramen joints, cafes that you can choose from. The building has a lift ( a big plus especially when you have to cart your heavy luggage)
The apartment itself is spacious, well lit, with lots of sofas to lounge around but has the tiniest of bathrooms. The washbasin is even tinier. So tiny that water splashes on the floor everytime you use it. We felt the shower stall was small and a trip and fall hazard. The second bedroom barely fits one single bed with one window that opens to the wind shaft. If you open the window, it gets a little noisy. Carry your own detergent for the washing machine because they don't provide any. The AC in the bedroom is really effective.
I wish they'd put in as much efforts on the amenities as they've on the decor. No extra bed linen (even on request), no coffee maker (can't go out everytime for your caffeine cravings), the arm chair next to the bed had the leather peeling off, no facial tissue,table mats, full sized ironing table ( these ammenties are the norm in most AirBnbs). The kitchen has just salt, pepper, sugar, instant coffee. All AirBnbs we've stayed in Europe provide oil, sauces, spices for basic cooking. It doesn't make sense to buy all of these for a short stay.
The property managers are very helpful though. The water heating unit had a problem late at night and they sent someone right away to fix it. We were given a change of towels on day 3. They are quick to respond to your messages. Gaby gave us good reccos on tapas bars and paella. They kept our luggage for us till evening, after we had checked out and let us use the bathroom.
