The location as far as proximity to the main nightlife restaurants in Centro Storico was good. Plus a taxi stand on corner. The access to nightlife may be too good for some, as there is bar below that could be noisy - although we were there over New Year’s. Unfortunately we did not get to castles, so cannot comment on proximity to those attractions. The place was clean, and kitchen adequate for light meals - it is not set up for cooking full meals. All in all it worked well for us, although maybe a bit small / open for unrelated adults needing some privacy.
