Luis is a very kind and communicative host!!
The apartment he provides, is also great. It has everyting one needs, a lot of space and is very bright.
The location is very good too. There are many Resttaurants, Bars and Cafés directly in front of the house and Metro and train Station is very near too.
Also don't be opposed to the fact that you have to share the apartment with Luis. First of all, he isn't there for the majority of the time anyway and even if he is very kind and easy going.
