We stayed in this apt for over one month, me and my husband and our two pets.
The location of the apartment is its highest value. Poblenou is the best neighbourhood you can be, being at one block from the Rambla with shops and restaurants, and pretty near to all transport means it was a great place for us to discover Barcelona, also the beach is just two blocks away! Be mindful that because it's a quiet neighbourhood things pretty die at 9 and there's barely people outside (at least in winter) but still is really safe. The apartment has everything you need to stay, washer, drier, kitchen utensils etc, and I believe is fantastic for shorter stays, and a real max of 2-3 people, even if there's plenty of beds, it's a really small place and if you're going to be living in there more than just being outside all day, it's going to get crowdy, also, there's almost no windows, so it's pretty dark all day.
The communication with the hosts was a bit weird, at first we were really worried cause we were traveling with two pets and our time schedule was complicated at arrival and they never made us feel safe about it, even until last minute when Mario got sick and Alina had to cover for him, she managed to be there and wait for us, but there was a layer of fear we had that shouldnt have happened. We also got one key only for the two of us and got told if we lost it or smth there was no replacement, we had to make arrangements all the time so one of us could open the door, really insane, but at least we discovered that for checkout you could leave the key on the inside so we were able to leave earlier than the specified time.
On the overall we recommend it and we're thankful for our stay.
