This is a great location. Hanne, is very accommodating, kind and respectful. The flat is clean and has a beautiful view of the marble dome church. There is a charming courtyard that is not visible from the street, but is quiet and lovely. There's an awesome bakery directly across the street and just a 10 minute walk to a major train station. There is a separate entrance that allows for easy coming and going. For elders, (we are among you), there are a lot of narrow spiral steps to climb get up to the flat, but that is fine assuming you don't have too much baggage and you are in good shape.
Cheers!
