If you are looking for an authentic stay in Barcelona, Esther's apartment is the best choice. She is extremely sweet, generous and nurturing. I traveled by myself and she took care of me as if I was her own family. The apartment is in the Gothic Quarter, a 15ish minute to the beach and in the middle of the city, 10 minute walk to the closest metro and super close to museums, shopping and food! I will definitely be returning in the future! The terrace was my favorite part of my stay, watching the sunsets and sunrises from the top of the building is beautiful! The flat is about 16 set of stairs to get to it, but in my opinion it is more than worth it. Stay with Ester, and you will fall in love with the city.
