Host, Lera was very nice, waited for us on the parking lot outside apt. at 11pm which was very nice. Language barrier was hard at first, but she was cooperative and we got to know everything we wanted. Room was clean and cosy with very comfortable bed, nicely equipped which was a big plus. Only problem was that we couldn't lock the door from the inside, or more importantly the outside (since there are other guests too, that we don't know).
Rule about not showering after 11pm surprised us, but we did shower very quickly after that time once or twice and it wasn't a problem, so I think it's just a rule to have some mutual respect for host and other guests.
Location was nice and safe, not far from metro station and small stores, had some restaurants around too. Quiet at night.
I think price is moderate compared to other offers.
I would recommend this place for anybody who doesn't want to be strictly in centre of the city that can be loud 24/7, but yet wants to be close to anywhere important in Barcelona.
PS. Cat was very funny.
