Javier's apartment was great. It was clean with fresh sheets and plenty of towels for our usage. We had everything we could've possibly needed (hairdryer, iron, espresso machine, plates, wine glasses, etc.). He left us some food, snacks and drinks what was very kind of him.
The apartment is situated in a quiet part of Barcelona only few minutes away from a Metro station, so you can easily reach any place you would want.
Javier is a really caring person, he spend a lot of time to show us everything (in his apartment and in the neighborhood). He explained us how to reach the bus station during the night when we leave Barcelona and ordered us a taxi at the end.
