The apartment is located perfectly, about 10 mins pleasant walk to Sagrada Familia and having very close Metro station is an additional plus! Another nice thing we noticed is the neighborhood was local and friendly people. Super markets and local breakfast places were right downstairs.
Regarding the apartment itself, only thing we were a bit surprised was that the apartment much bigger in pictures but that is mostly the case. Everything was clean, well prepared with nice balcony if you smoke. A cozy apartment with nice colors add to the ambience. Kitchen had all the necessary crockery. One thing I like to mention here is that the bathroom didn't have any lock which was a bit inconvenient but clear communication resolved this problem :)
I would like to thank Sito and his colleagues. All of them responded right away if we had any questions. We had a great stay in Barcelona and we would most likely book the same place if we go back again...! Highly recommended for 4 people though 5th can also adjust easily.
