Mat is an excellent host and very flexible.
He has converted the basement into a lovely mini apartment. There is kitchen with a stove and fridge, a washer/dryer, hair dryer, tea, cups, plates, towels, etc. Everything you get from a hotel and more.
The bed is very comfortable and there's plenty of space for your clothes and personal stuff.
There was even a bottle of wine left on the table as a welcome gift which we thought was a nice touch (even though we didn't drink it because we are just not big drinkers and thought it could be used by the next guest).
The apartment is a 2 minute walking distance from the Rique metro station which is super convenient.
We'll definitely be staying at Mat's again.
