We were a group of 6 people, it was our first time in Madrid. Everything related to the apartment was perfect - the location, the space, the host - Alfredo welcomed us warmly, showed us around the apartment, gave us valuable tips for the city and answered every question we had. We had no trouble finding the place (starting from the airport) as Alfredo has sent us extremely useful information on the topic.
The apartment itself is cozy and warm and has all the basic essentials a traveller would need (no need to jump to the store (which is 1 minute away btw) right away!). We appreciated a lot the washer, the hair dryer and the really very fast wifi.
We recommend the place and would be happy to stay there on our next visit to Madrid.
