Mr. Ricardo was not only generous but a very nice person. his house location is close to petty much everything, you can either walk 3-15 mins to every thing or take Uber for 5 euros only.
i recommended everyone staying at Madrid to stay here if it was soley for location, the hospitality is a big plus! not mentioning he is very very responsive. the longest we waited was 5 mins.
noting mr. Ricardo gave us instructions to his house and pictures several times up until he knew we got home. so you won't get lost
