The apartment is very well located, a few minutes from the cathedral, shops and restaurants, 10-12 min walk to the port. It looks exactly like in the pictures. The building is newly renovated, the apartment also. There are 2 supermarkets basically just around the corner, one of which is open on Sunday too.
Communication was excellent with the host, we have required a high chair and a crib and their were provided.
However, keep in mind that it can be quite noisy at night especially in the week-ends, so if you have trouble sleeping bring ear plugs :) but this is normal for the quasi-totality of the apartments in the old town.
