Good apartment in perfect location in historic city of florence. The term "luxury" is a bit overstated though: The interior is pretty much fully IKEA and dishes, dishtowles were a bit dirty/stained. There was only one hotplate for cooking. Overall the apartment was clean and there is good air-conditioning.
Concerning communication: Good communication and many tips for restaurants etc. Though the extra fee for late check- in (from 7 pm) was in my opinion not adequately transparent (we were at the apartment 5 minutes past 7, so that was a bit strange)
Good apartment, very good location, not luxury though!
