They are very great host. Very nice people and you can always ask them questions and expect to get a respond in the next minutes.
Luis is very nice too (the porter). The place looks new and it is very clean. The flat is equipped with everything you need for a long stay except a washing machine for your clothes. But, don't worry, you can go to one very close.
Otherwise, the flat is very cosy and the bed of a great quality.
Hope you will enjoy your stay like I enjoyed mine!
