If you come to visit the city and your intention is not to be at home at all then it’s ok. You have to be very easy and philosophical To feel yourself at home. The host is nice and the place is very central though not the nicest area of Barcelona. Though it’s pretty quiet considering the active night life around. It’s actually noisier during daytime when kids are having their break between lessons. But that’s not really annoying. Annoying maybe to be able to run into other guests on your way from your bed to “your” bathroom. The bathroom is not shared but the space between it and the bedroom is.
