We stayed at Gianluca’s for two nights. The first night was totally fine, clean, nice place. The second night we went to a show at the forum and returned to find our bedroom door locked (the door only locks from the inside, so we didn’t have a key... and apparently there was no key in existence to open the door). Coincidentally our host and his friend also arrived soon after we returned (about 1:30am?)... our host seemed reluctant at first to resolve the situation, thankfully his friend helped out by essentially by removing the hardware from the door. Overall we feel the scenario could have been handled much better.
I would simply suggest that the door latch/lock system be replaced to better suit the convenience of guests and host!
