Felix’s place is fantastic! A great central location and very comfortable for 2 adults. It is a 15 minute walk from all of the hot spots in Madrid. The air conditioner/heat are great, the wifi is strong and the lighting and fresh air with the 3 windows is awesome. If I had one “negative” comment, it would be the 5 floor walk-up. I was expecting the walk up as most places in Europe are walk ups, but I would be mindful of that if going with someone super elderly or super young children. Overall, it was a fantastic stay and I would stay there again.
