Samuel's flat was clean and convenient and we give it a big thumbs up for the terrific location which is right walking distance to everything, being right in the middle of the old part of the city. It was fun to peer down into the narrow street below us from the living room and to see the Duomo lit up at night from our bedrooms. Two things to bear in mind are parking and stairs. If you arrive by car it may be complicated. Our GPS system got completely confused (others seem to have had the same issue) and wanted to send us down one way streets the wrong way and many of the streets have restricted access. Samuel was very helpful and came in person to guide us to the parking garage he had recommended. He then helped us wheel our bags to the flat. It is on the top floor of the building so try to pack light. It's roughly 90 steps to get to the top. All in all, it was a very good experience.
