I stayed for a number of days in U232 recently and enjoyed my time there. The hotel is a few kilometres from the central part of the city, so if you are site seeing and like the Ramblas area, then you'll need to use taxis or public transport. Luckily, the "Hospital Clinic" blue line metro station is about 150 metres away and is a very useful and cheap way of linking into the city centre or to both the Sants Estacio and Passeig de Gracia stations (travelling to airport, or Circuit de Catalunya respectively).
The rooms are pleasant, if a little small, and there is complimentary and fast wifi available. There is a good selection of bars and restaurants in the area. Breakfast is a buffet and offers a reasonable choice of hot and cold itemsMore
