Stayed for 4 days at Francesco's place. I really enjoyed my stay. The flat is small, but the space in the appartment is very well organized, you have everything what you need! Generally, the appartment is really cozy and nice :)! Also there where some nice details: like filtered water placed in advance in the fridge, so I had nice cold drinking water as soon as arrived. Toasts and jam were in the appartment for a prompt snack upon arrival.
And of course, it is very important, that communication with the host was effective and prompt! Francesco was very helpful!
The check-in and check-out procedure was easy and smooth.
And the main thing to mention is the brilliant location! You are staying close to all main attractions (I just walked everywhere without a problem), in the middle of vibrant, full of life Trastevere, but at the same time the street itself is very quite.
I highly recommend Francesco's appartment, especially for solo travelers like me :)!
