We had an amazing stay for seven days at Leo and Jose's place. Barcelona is a city full of life, trafic and noises both day and night, but with that just outside our door, the room (and terrace) was very quiet and well, sunny. We shared a small kitchen and bathroom with two other guests, but had no troubles with sharing - acutally there was no sign of anyone living in the apartment but us, besides when Leos dog ran into our room to say hi in the afternoon (Obs: a very cute and friendly dog!). We arrived late late at night and even though the "check in" "closes" at 22.00, Leo was very friendly to recieve us and shared some amazing resturants and sights with us before going back to bed. You could tell that Leo is very used to give guidance and knows the city and its tourist.
We would really recommend this room. We are two students on a low budget and we walked around the city every day. It takes about 40 minutes to La Rambla and about an hour to get to the (nice) beach. It is a bit a distance to walk multiple times a day, but with a good plan for the day, it can totally work (or like take the metro or rent bike). Very pleasant experience!
