We stayed in the apartment for 10 days in January - February 2015. The location is perfect, there are bus stops and metro station within walking distance. Here you won't see crowds of tourists like in The Gothic Quarter, but many sights are a little bit far.
The flat is small but cozy. We were staying during the winter time, so it was cold inside. Pep was so kind to quickly bring us the second heater. This has greatly improved the situation, but the apartment was still a bit chilly.
The apartment has a microwave, washing machine, small fridge, and Pep brought us a kettle, which was not in the apartment initially. Another feature - when you turn on the kettle (or a washing machine) with two working heaters, it can suddenly lead to the electricity turn off. Therefore it is necessary to turn off one heater (and do not forget to switch it on later :)).
We want to say many thanks to Pep for allowing us to stay in the apartment until late at night the last day, because we had a night flight.
Overall, we enjoyed staying in this apartment. Pep is very helpfull and friendly host, always willing to help. The apartment is great if you are going to walk all day and not spend so much time in it.
