Petruz and his wife are lovely, hospitable hosts who made us feel like guests in a friend's home. He greeted us warmly in a nearby square with cold beers in hand. He was so helpful when my boyfriend lost his phone. The area is lively and central - walking distance almost everywhere we wanted to go, plenty of metro stops, and available taxis.
This is a wonderful place to stay. However, I wish I had known a few things before I booked:
1) I don't smoke so the smell of smoke bothers me a bit. While the room itself was spotless and smelled nice, the main areas are markedly smoke odored.
2) They also have a dog Robbie - who is adorable and so sweet but comes with the usual dog smells (especially in the bathroom).
3) For anyone with injuries or limitations - this is a steep, third floor (by American measurement of floors) walk up.
4) The room and apartment are very dark! It's also part of the charm of the area but getting ready at night was a bit difficult.
5) The AC was broken - which is unfortunate in the middle of the summer.
6) The area is very central so it is incredibly noisy - especially late into the night and early morning.
None of these issues dampened our experience significantly but I think they are worth noting for future users. All in all it was a positive experience and we truly had a fantastic time in Barcelona!
