It was very nice that Nicola allowed me to check-in even at 11pm and to let me stay at such a huge place even though I was solo. Rooms are pretty, colorful and simply furnished. I had a washer&dryer in the kitchen which is not easy to find outside in Rome. Two bathroom will be useful for more than one travelers.
More than that, Nicola and his son are really nice and are willing to help me. When it comes to trouble (one shower head was broken), he gave me a quick response and responsible. Now I know the reason why he's one of Best Hosts.
