Marco is a really sweet guy with great energy. However, my experience in his flat was mixed. The location was great -- the neighbourhood is low-key and residential, with some bars and coffee shops that served fantastic cornetti for breakfast. The check-in was easy. The connections to the centre of the city and all train stations were really convenient!
However, the flat itself, and especially the basement room, were not clean. I know that Marco is extremely busy these days, but I was surprised to find that the room was evidently not taken care of after the previous guest, with dirty towels and hair on the floor.
Other than that, the room is cosy and looks like what the pictures suggest. However, it is much darker than in the photos -- there is very little natural light in the flat, and obviously no natural light in the basement bedroom where I was staying. This also affects the circulation of air, so it's a little damp and musty.
