Nicolas is a great host with very friendly communication and his apartment is awesome. Highly recommended!
Just two things to keep in mind for would-be travelers:
1. The apartment is on the top floor, so it can get quite hot in the summer.
2. There is no stove, so keep that in mind if you are used to using more than a microwave to prepare your meals.
Neither of the above was a big problem for me, however, it's good to be aware of them beforehand.
