Overall it was a convenient and good stay and really appreciate hosts timely response to messages. couple things to call out ;
General - the door to the building is mostly left open which is a bit of a concern. We closed it every time but once we came home it was always open.
Get ready to climb up 4stories its the 1below top floor.
Its very chilly in the winter! When we visited it was 0-5 celcius in rome so we needed the heater to function properly but we had no luck.. we used every blanket/sheet/sweater we had to survive the nights.
Location - 4/5 the bus is great and right in front of the place but if you plan to explore touristic sites other than Vatican you cant walk to much. Nice neighborhood and carrefour express very close by for market needs.
Bathroom- 2/5 this was probably one of the worst I have ever seen; toilet seat was broken, you had to hold the shower handle there was no place to hang it, sink drain was clogged, it was such a tight and claustrophobic space with an weird smell. Definitely needs an urgent reno.
Kitchen- 2/5 again very outdated no coffee or tea maker which is a typical necessity in every hotel or home. We don't usually cook or use kitchens on vaca anyway but even to make a cup of tea we had to boil water in a pot. Stove gas not functioning properly and overall not a great kitchen space.
Rooms- 4/5 comfy bed and clean sheets not much to say for the room you get what you see.
Wasn't able to meet the host got the keys from a nice Italian lady without any english (i believe the host had referred to her as the cleaning lady). It was bit of a hassle to find the unit at first because the chain of communication was very tough; host->host's friend->cleaning lady->us.
I would say it wasn't the best choice for us but could be different for others.
