Overall, our stay at Gianfranco's home was lovely and he was a great host. The house itself is wonderful - he has been renovating it for some time now and has a lot of beautiful features along with a lush, serene terrace. It does feel like stepping into another world as it is right next to Zoológical Nacional and you can even hear animals as you are having your morning coffee. We enjoyed the sauna tremendously and switched between that and the cold bath often. He also provided plenty of recommendationd in the area. We did struggle a bit with the keys to get in the property, but that is expected with older houses.
The location is excellent with plenty to do in the area and incredibly walkable. Serro San Christobal and the Furnicular were less than a 2 minute walk in either direction. I will say the area can get noisy at night, especially over the weekends due to proximity to bars. Gianfranco did provide us excellent earplugs and made mention to that ahead of time to us so we slept well
