This is great place to stay for a solo traveler! This was my first time in Barcelona (and Spain) and the location in Gràcia meant it was a short walk to metro, shops and the many cafes, bars and restaurants in the neighbourhood.
The room was very clean with air conditioning and a good amount of space so you don't feel crapped. Shared spaces include living room/kitchen, which I didn't make use of, however, the washer/dryer came in handy.
Makes for a great homebase when exploring the city.
