Location, location, location! This flat is right in the middle of cobblestone streets and alleys, filled with restaurants and music. It's also walkable to the waterfront and lots of other sites. It's cozy as described but worked great for the two of us. One note - the closest you can get with a car is about a 3 minute walk away, and you do have two flights of steep and narrow stairs to navigate to get to the flat. (This just adds to to experience, in my view!)
Check-in and check-out were easy, and we got lots of great local tips as well!
