The apartment has spectacular view from the windows and balcony to Sagrada Familia. Great location. The apartment was clean with towels for each guests. When we came the apartment was cold but you can put the heat on (but you need to figure it out, one of the rooms were hot and one was still cold). Overall we would recommend this place, the only con was that the elevator was broken couple of times over the 5 days so we had to climb 9 floors everytime.
We would suggest to offer some drinks options such as instant tea or coffee (especially in the winter time).
Eva&Jack recommended the stasher app for storing the luggage after check out, we recommend to do that as well, it costs 5€ for one luggage.
Thank you, we had amazing time in Barcelona.
