I will confirm what everyone else says: Federico was the BEST host. He even secured a reservation for us at a restaurant that is otherwise booked for weeks. He should win an award and teach others the art of being a gracious host.
The apartment is beautiful, and the location is perfection. It’s easy to walk to much of the city. If you turn left when you leave the building, there is a wine store and just past that is a convenience store should you need more than wine. At night we loved sitting in the window seat, window open (of course), drinking wine, and just taking in the city.
Although I would absolutely stay there again, I have to caution that one of the baths does not have a shower, just a tub with a shower head. The couple we traveled with used that bathroom and said it was challenging and they cleaned up a lot of water. If you’re like us and not used to that style, or if you have physical challenges, it may be something you want to consider. But really all things considered, it is a very small inconvenience for what you get with this apartment and Federico as your host.
