The Good: Flat is located in a quiet street even though its practically in the center of all sites to see in Florence. The place is clean (except bathroom issue) & as presented by Ad pictures. Lorenzo also provides the best quality bed sheets & towels hands down. The Not-so-Good: Check in thru Keesy App is not user friendly & had a hard time checking in...it took a good 90 mins of looping back & forth & I finally gave up & emailed Lorenzo to fix which he did morning of check in. We got to flat at 2:30pm as agreed by Lorenzo that he can accomodate us earlier but App won't unlock door, called Lorenzo, he said he'll call Keesy, called us back 2:58pm to let us in...we stood outside in the rain all this time! My biggest issue, mold in the bathroom. Now to be fair to owner, he may not have known issue since he has operator running the flat, but now he should be aware of it & fix issue. This is a red flag to me as it presents health issues to guests. Florence was great otherwise.
