Everything was great from the beginning to the end!
Juan Alfonso is very responsive and kind. The apartment has the perfect location to explore Madrid on foot. I was a little bit nervous about the bar noises in the night because I tend to have insomnia, but the noises becomes withe noise and we slept very good. I had to work a little bit and the wifi was awesome, I am a video editor so this was a nice plus!
Overall we had a great stay and I totally recommend staying at Juan Alfonso's apartment. Thank you so much J.A.!!
