Went with my wife for 4 nights. Hotel is "relatively" cheap by Barcelona standards, but we tend to only use the room to sleep and shower etc, so not worried about huge amounts of facilities, or even breakfast which is easy enough to get in the numerous cafes nearby.
Great central location, right next to a Metro station, but that's the best thing about it. Room was small, the double bed pushed up against the wall so I had to climb out of the end of the bed (also makes it not easy to get out of without disturbing your partner). The sliding doors out onto the balcony were not airtight so a lot of outside noise got in, especially with there being a nightclub directly opposite that is open until 5 or 6 in the morning (you can't hear the club itself just the noisy people coming out of it!!) Air-con was very good but quite noisy. Staff were all very friendly and all spoke English.
Bathroom was ok apart from the sizeable damp patch above the shower, but had to go down to reception to ask for more toilet paper as they clearly didn't check to see how much we had and there were no spares in the room. Small fridge which is adequate, but a completely unnecessary desk in the room which took up a lot of room that would have made the room feel larger without it?
So, in all, a compromise - you do get what you pay for, but I would still expect to not have a large damp patch on the ceiling or hear quite so much from outside. If you can live with that, this place is ideal!
