Everything was good.
Apartment is big enough, even for the big company. There is food store and some restaurants close the flat. Metro station is very close too.
Marco and his father are very welcome and friendly. Marco gave a lot of helpful advices about Rome.
Also we had some problems with tickets to Rome - flight changed twice - and Marco readily help us with booking and time of check in.
If we go to Rome next time we would definetly stay here again.
