Apartments and hotel are completely separate
It's important to note, since it's not clear from the booking sites, that Santa Maria Degli Ancillotti and Il Falchetto apartments are separate entities. We were given keys to the apartment and did not enter the premises of the hotel which is down the road with a separate gate. In fact they could not even accommodate us for breakfast or dinner since they were fully booked.
We arrived around midnight and rang the bell at the hotel. There was no answer for several minutes and when someone finally answered she said check-in ended at 10 pm and to return tomorrow. Only when we told her that we had 2 babies in the car did she agree to come out and meet us. She was very unpleasant and continuously scolded us for arriving at that hour (despite the fact that the reservation stated that late arrivals would be accomodated). In fairness we later understood that it was a family run business but beware that if you arrive past 10 pm you will not be welcomed!
The apartment itself was comfortable, clean and the kitchen was well equipped with everything we needed to cook.
There was no cleaning service and towels and sheets were not changed during the 5 nights we stayed.
The location was a perfect point from which to visit various towns in the area. The view was beautiful.
