We had a great stay here. Our host Sergi made everything very easy.
The apartment is not huge, but more than makes up for this by being in such a great location, central to everything. it's a very easy place to walk most places you will want to go in Barcelona and metro station is just outside on La Rambla. The area is very busy at all times so we never felt unsafe. Because of this the apartment can get noisy, but this is the trade off for being right in the middle of things. Everything in the apartment was clean and well appointed, if somewhat basic.
Overall enjoyed our stay here very much, would return and the apartment was great.
