Room is as in pictures, it was really warm for December when we were there. There is no free parking around and host couldn't tell us where we could park but I've found it myself, not really far - just Google "Calle de San Dacio" and it is like 800m from apartment, across the bridge - we parked there a few nights for free without any issues.
It was listed that this place has a Washer - but when we asked to wash our clothes owner said that "generally it is not allowed" so we didn't want to push it.
Generally this place is not really great for first-time visitors of Madrid as it is a bit far and it is not really well connected, but if you come by car and want to chill for some time it is really cool. We used gym for 2 days and it was great, as it was winter we unfortunately couldn't use the pool :)
