We had a great time staying at Xavier's place!
The apartment is very nice- clean, looks just like in the pictures and has everything you might need (even an iron and a hair dryer :)). It is also well located- there is a metro station just down the street and it is only 10-15 minutes walking distance from the city center.
Xavier was a great host- very nice and answered all of our questions quickly.
To sum it all- very recommended apartment!!! Thank you Xavier!
