David was an excellent host - he was very quick with his responses and advised me on any questions I had before and during the trip. Check-in was seamless: He was able to accommodate earlier check-in for me (thank you!) and was handed over the keys to the flat by his housemaid upon arrival. The flat was sparkling clean, stylish, and fully-furnished (great if you want to bring back some things to cook!). Location-wise, it is about 5min walk to La Latina station and 10-15min walk to San Miguel Market. The El Rastro flea market (on Sundays) is literally right outside the flat, which was a cool experience. I felt the location could've been a bit more central, but Madrid being such a walkable city, didn't find it to be much of a problem. The bed and pull-out couches were both comfortable. Overall, great value & would highly recommend to others!
