We really enjoyed our stay at Esther's apartment in Barcelona. She met us at the apartment exactly as planned and provided detailed directions on how to get to the building in advance of our arrival. The apartment has a ton of character and is very unique, atop an apartment building in the middle of the Born district. It is a great way to spend a few days living like a local in one of the best parts of town. The views are wonderful and the most attractive part of the place is undoubtedly the deck. It has a table and two chair that is perfect for morning breakfast or evening drinks for two. As advertised there are quite a few stairs, which we didn't mind, but it is something to be aware of.
If you want a five star hotel, this is not for you. If you are looking for a cultural way to experience Barcelona, this is the way to go. With that being said, I don't think we would stay here for more than three nights due to the small size of the apartment.
