We stayed here for 3 nights, and were greeted amicably by Jonathan upon arrival. He was a wonderful host, and very friendly. He thoroughly explained what we had access to in the space, how everything worked, and what was available for us in the kitchen, along with fridge space. The room is below ground to our surprise, but not our upset- we felt very safe, comfortable, and confident to leave belongings there during the day, while we went out exploring. We saw Jonathan a few times in the kitchen during our stay and he was always willing to answer questions and recommended places to visit and eat. We even met a couple of other people staying within the apartment who were nice and respectful.
I highly recommend this place if you are staying in Madrid for a few days. Very affordable, incredible value for money, amazing host and a great location. Thank you very much, Jonathan!!
