Apartment is great, and location is convenient and quiet. We enjoyed coming back at the end of the day to unwind here.
When we went to book the apartment, we were surprised the stars were lower than we thought they should be. After staying at the place, I think this has more to do with the management of the apartment than the apartment itself.
I were a future guest, or the owner, I would want to know the following:
1) There needs to be a better check-in process. The current process is you call when you arrive at the door. They then give you the code to enter and then you go upstairs to the unlocked apartment to get your keys. The problem is: A) what if someone doesn't have a working cell phone because traveling abroad, B) no one answered our call the first time, and C) they will charge a 70 euro fee if you check in after 7, which seems silly given no one was coming to meet us. SOLUTION: Send the guest the code via email or whatsapp or the airbnb app at 12 noon the day of checkin and allow the guest to check-in at their convenience.
2) The apartment was not perfectly clean - in particular, the floors need to be mopped, especially in the corners. I would take off my shoes when I came in the door and go barefoot, so I could feel (and see) that the floors were not clean.
3) Trash takeout is poorly explained and too much to ask of guests. Like many AirBnbs, they say "please take out your garbage when you leave," which sounds fine EXCEPT A) you have to find the barge between 6:30 and 8:30 AM and take it there and B) recycling is complicated - alternating days for paper and plastic / metal, so to recycle we would have had to start planning 2 days before checkout. I was traveling with an Italian friend who had previously lived in Venice, and even she found that they asked guests to deal with this to be onerous. SOLUTION: the management company can / should do more -- either very clearly explain well in advance what is needed (and explain why the management company can't take care of it) or just take care of it when you have the cleaners come.
In short, great apartment, but it's not clear to me what the management company is doing to earn their fees.
