Very spacious apartment, it is on a fourth floor and there is a small elevator, less than 10 minutes away there are two metro stations, it is steps from the Magic Fountain of Montjuic, and the Arena Shopping Center, very quiet neighborhood. Below and next to it, there is a tapas and beer restaurant, which for us did not mean noise problems or something like that, we only enjoyed a few beers and some delicious olives.
The apartment was very clean and had comfortable beds and large closets, and what I loved, which is hard to find in Europe, is single beds and bedrooms, the rooms are a bit cold in winter, we were there at the end of February there and outside there were about 8 degrees of temperature.
Kitchen, dining room and bathroom, good shower, there is a balcony. If you have to buy all your things, there were no basic things like hand soap and / or shower in the bathroom, shampoo, or salt, or sugar in the kitchen, there are also nearby mini-markets to buy, those that work all night.
We had a very good stay.

David, thank you very much. I would go back to your apartment without a doubt.
