Even though I very much appriciated Sol, two things need to be said as they are not clear from the description or other reviews:
(context: we were 3 (female) colleagues staying in Barcelona for participating to a conference)
-	The add presents the place as a private studio, however these are 2 communication rooms. So if you are 3 (as was our case), the third person has to cross the double room to get out, go to the toilet, etc (so little privacy). I should have read the discription better, instead I relied too much on the pictures which showed a separate room with a third bed (but this is actually Sol's room, so it is not for guests)
-	In addition, the place is very well situated, however because of this there is really a lot of noice at night of people in bars and restaurants on the plaza downstairs. In the morning you then hear the garbage and cleaning trucks doing their work...
