We stayed 3 days in in Barcelona U232 hotel with my wife between 3-6 August 2008. Hotel has very futuristic interior design. Rooms were clean, staff is friendly. There are many items with quality in the room like (shaving kit, liquid bath soap, shampoo etc.) Free wireless internet connection was enough fast. It's not in the heart of the city but hotel has a close underground station, it's not a big problem.

The U232 is very well located, close to Avigunda Diagonal, one of the most important avenues in Barcelona.
I have stayed many times there for business and personal trips.
The rooms are very confortable, good beds (even if they are not the best) and very clean bathrooms.
My only negative comment is the quality of the food in the room service, I asked for a club sandwich and it was not very good, compared with the club sandwich that you can get in any international chain hotel. I can not say anything regarding breakfast or dinner since I have not eaten there.
Overall very good experience !!
I will recommend the U232 for its quality and very good price.

This was my first stay in Europe, but I was prepared with how small the hotel rooms would be as well as the potential issues with the bathroom (half glass shower door). The front desk staff were extremely amicable and helpful, especially when inquiring about toursites and the best ways to get there. Though we had some issues functioning the shower (though there was a full shower door, using the shower full blast caused the bathroom to flood - using the portable shower head fixed the issue), the staff responded to this repair right away. The complimentary internet service and relaxing library were unexpected, yet very appreciated amenities. The room was very modern looking and clean, though I would have appreciated some English channels on the TV. I would definitely stay at this location again, though note that it is located just north of the Eixample district, which is a little ways away from the "downtown" of Barcelona (near Las Ramblas).

An excellent choice for a few days in Barcelona. What's with the picture on the tripadvisor webpage, though ? I don't know what it is, but this red thing is not the hotel. U232 is smart without being silly, efficient without being slick, friendly without being creepy, and good to retreat to when you need a break from the sightseeing. Gratifyingly huge bath; chilling air-con. Did not take breakfast there, but the bakery two blocks down the street was marvellous. Only hiccup is the ongoing work on the metro interchange between L3 and L5 at Diagonal station, which makes the journey to and from the town centre a little longer and more awkward than it will be when the work is done.
