Stayed here for 6 nights in early september and paid 69 euros a night (!) through Venere.com. I honestly don't think I could have found a better deal in Barcelona. I got a spacious apartment with 2 singles, a kitchen (including a refrigerator!), bath tub, sofa, dinner table and a private balcony. Also, the air-conditioning works fine and everything was spotless (daily maid service). Yes, the interior is a bit outdated (think 70's style Costa Brava) and it's a little worn here and there, but nothing serious and the beds are fine.
The hotel seemed nearly deserted when I was there and I had the rooftop pool to myself a few times. Good thing, too, as it is very tiny. About 4 by 5 metres and 1 metre in depth. It's ok to cool off in, but don't expect to do any serious swimming here.
Using the Vallarca metro stop (line 3) means you'll have to climb a few pretty steep hills before reching the hotel. Not cool if you're carrying a heavy bag in hot weather after a flight. Luckily the receptionist mentioned Avinguda Tibidaba (line 7, goes directly to Placa Catalunya as well). The distance to the hotel is about the same (about 400 metres I'd say), but it's flat. So look up that one before coming to the hotel. I highly recommend the place.
