Great place, exactly as described with the balcony as the perfect place to wind down after a busy day. The secure parking across the street is a big bonus if you're travelling by car. All the tourist sites are walking distance from the flat.
Santo is the nicest host, always quick to respond and superhelpful.
One minor thing: there's some street noise and noise from the building. If you're a light sleeper, you might want to bring ear plugs.
