I can recommend this place for sure. The house was clean and very nice and cozy decorated. The host was great, he was absolutely fine with the late check-in hour, every morning he was offering us breakfast and tips where we can go to explore Madrid. The location is great, it is really close to the biggest park in Madrid - Retiro, there is a supermarket really close ( 5 min walking ). There are bus stations also within walking distance.
There is lovely big terrace where you can sit in the afternoon or in the morning, if the weather is good.
At first when i saw that our room will be right next to the host's bedroom i was thinking that it will be awkward , but it was not a problem at all.
The neighborhood is quite and the only noise is from the kids garden .
