The location was absolutely perfect. Short walk to anywhere you wanted to go (15mins to train station, 3 mins to Duomo). You didn't hear much street noise with the a/c on, so noise was less than other reviews led me to believe. The a/c was pretty week and acted like a fan; the room did not hold the temperature low. The toilet seat was also broken when we arrived. Lastly, there were some persistent mosquitoes in the apartment, but not sure where they were coming from.
All in all, the value of this place was impeccable. Vacation is meant to be spent seeing the sights and little time in the room, so the amazing location and hospitality outscaled any issues with the apartment. Can't beat the value.
