First of all, Ferran is a great guy. The one you can really rely on and who can help you if you need help.
Second, the apartment is best what you can get for money you are paying. It is neat and warm, making you feel like you are living in Barcelona, not just staying there, which puts the whole experience of travel on a completely new level. In the apartment, you have everything you need, even espresso machine and ironing equipment, which was, frankly, a big surprise. You don't get that often. Regarding the position, it is absolutely perfect. It is quiet in the morning, since it is in the quiet street, so you can sleep late and peacefully. Yet, it is also very close to La Ramblas and very heart of the city, which you can reach by foot and enjoy all different beauties of this magnificent city. The metro station is, literally, 90 secs walk away and by metro you can reach whatever you need in Barcelona. The marina is also on walking distance, so you can easily get there and enjoy the look of the sea, visit very big shopping mall by the sea or visit beautiful aquarium, one of the biggest in the world.
Anyhow, if I go to Barcelona again, I am sure that I will look for Ferran and his beautiful apartment, to make my visit even better.
