Lorenzo was really helpful and friendly. We had really late check-in and very early check-out, but it wasn't a problem at all (also no additional fees for that, and it's great). He knows a lot about Rome, so ask him for any recommendations.
Place is very cozy and clean with all the facilities you might need. It has cool capsule coffee machine, so you can enjoy your morning coffee right from the bed :)
It totally corresponds to the description and all the photos are relevant. Near the place there is supermarket, and some places to eat/drink. Closest metro station is 20 min to go, but there is a bus stop right near the apartment, so probably you can use it (we didn't use it though). One night we walked from Colosseum, and it took 45 min fast pace walking for us to get to our place.
The only thing that it might be a little tricky to find the front door that leads to the porch with elevator, so make sure that you are connected to the internet or turn on your cellular network just in case.
Definitely recommend this place!
