The location is great, it's just a minute's walk from Mercado de San Miguel. It's also right beside the Convento de las Carboneras, famous for their pastries.
The apartment is spacious and charming, with a lot of windows and natural light. The living room was big, the kitchen was complete, bed was very comfy. Fast wifi, good TV, heaters and washing machine. I enjoyed the bath tub too. I would recommend adding light in the bathroom as it can get a bit dark at night.
I was not able to meet Jesus, but he was very easy to reach via chat. So easy to talk to, and accommodated my request to leave my bags before the check in time. His cleaners were also very nice and helped me with my bags. The apartment is on the 3rd floor and there's no elevator in the building, so they were really life savers!
Over all, I had a wonderful stay at Jesús' apartment. Gave me a taste of Madrid life. Thank you, Jesús!
