Nicola is very welcoming, he sends a lot of very usefull tips about what to see and where to go in Roma ;
The appartment is really nice, well decorated, and the air conditionning was a bless for our trip in july with 40°C outside.
The cleaning is perfect.
The fridge is quite small though, so make sure you go shopping for food or drinks every other day max (the supermarket is very close).
