The appartment is really nice. Just like shown in the pictures. Clean and comfortable. Location is fantastic, in a charming, fashion area which is full of very interesting shops, restaurants, etc, and within a walking distance to most of the main tourist attractions. Miguel (Guillaume agent) was perfectly punctual, very nice and helpfull. He gave us all the necessary information. They were also very flexible with the check-out timing.
The only "but" would be the narrow stairs to get to the appartment.
I would surely come back and recommend.
