The host was really nice, he is willing to help you if you ask. The recommendations for restaurants and attraction in Madrid that he gave us were so helpful. Thank you! And the description to get the house was detailed so that I didn't feel any difficulty to find out the house.
For the room for two persons, it has a wide and comfortable bed.
Only one thing that I felt uncomfortable was about 'warm water'. Hot water is offered 24 hours, but I spent much time to use warm water in the toilet even if he taught how to use..... Really difficult to realize how to use it haha...
Anyway, the host is really nice and the house is near from Sants station! Good
