I can say - everything was perfect. Firstly the comunication system – mail and sms. Its gave me instructions a few days before I checked in and also during my stay, and moreover – after check – out. It vas not only nice, but very usefull.
The flat was clean and very well maintained. I appreciated welcome pack. It was very nice. For more.. Metro is just outside of the apartment which make it so convenient to travel around. And Sagrada Famila so close! Would definitely recommend if you want to stay close enough to city centre.
