Location is great and easy to find. Rooms are downstairs and there are 2 toilets + 2 showers shared among the guests (believe 4 rooms). Kept clean and everyone we met there were very courteous and nice. There is a nice shared kitchen with snacks as well.
Room was spacious with a cellar feel. We had the fan on to circulate the air.
One thing to note - Eduardo’s place has a washer dryer which is nice. We are not super familiar with how this particular type of washer dryer work so wasted a bunch of time so make sure you ask ;-)
Eduardo is a great host and very responsive. We were leaving in the late afternoon and were able to keep our luggage at his place - really nice to have the flexibility. Would definitely stay again if I return to Madrid.
Everything is walking distance - this location is also 1 min away from the Sunday flee market (el rastro), fun to check it out.
