The apartment is exactly as pictured. The lounge dining is very stylish and large with good furniture. There are 3 bedrooms, one double at the front and a bunk room with wardrobes, and the main room at the back. The main bedroom being at the back was a real plus for us, as we were a couple and the room was very quiet and had ventilation to the light well at the back. There is not much clothes storage int he main room, so we used the bunk room as our dressing room.
The bathrooms are small but clean and functional.
The kitchen is very well appointed, and has everything you might need.
The location is excellent, about 15 mins walk to the main shopping at Passieg Gracia, Casa Mila and Casa Batllo, and 20 mins to Sagrada Familia. It is about 30-40 mins to the more touristy locations of Gothic and El Born.
There are lots of really very good and not over priced restaurants (eg. Teoric Taverna Gastronomoica and ChiCha for example) nearby in Carrer Bailèn, Passieg St Joan and in between, and the location is extremely well served with supermarkets, bakeries and fruit and vege shops. There is a good market only 10 mins away.
Great location, and the only downside is that you need to expect that the traffic noise in this area is going to be high, but being on the 4th floor (level 2 in Spain) this is not unacceptable. You will be able to walk almost everywhere from here (taxis are relatively cheap and you can easily order them using the MyTaxi app), so make sure you have comfortable shoes, but if you haven't then there is no place better to purchase them than here in Barcelona!
