Great communication with the host (I mostly used the spanish) who leaves small attentions in the flat that is well equipped, enabling you to feel at home quite fast as it has everything you need (at least for my business trip).
Location is great with a supermarket 1mn walk, mall at about 10mn and metro station 5mn away, great if you're someone mobile who wants to move everywhere with public transports. But if you want to find Taxis thats also good since you are in between 2 main avenues there's plenty.
Sports room and swimming pool are small so don't expect too much of it. Haven't tried the Sauna.
Bed is very confortable ! Internet is very good and kitchen well equipped.
With all of this I had all the ingredients for a great stay !
