Madiano was a great host and was very responsive. He was able to help with all our questions and needs. He was also able to help arrange for a private car pickup for us from the airport at a pretty reasonable price and it is a real time saver.
The apartment was located close to both the Vatican City and the Pantheon with about 10 minutes walk in their respective direction. There are also many cafes and restaurants in the vicinity.
The beds were comfortable and the wifi speed was great in the first bedroom and the dining area, unfortunately not in the second bedroom.

The unit is on the third floor or technically the fourth floor if you consider the ground floor as the first floor. If not mistaken, I counted 61 spiraling steps leading up to the apartment unit. Given the older nature of the building, the stair designs are small and I would recommend that one walks up and down these stairs with great caution.
Other than that, we had enjoyed our stay there.
