Great host and very tidy place. Everything you need for a few nights stay in Rome.
Fabrizio reacts very quickly and is very accomodating. He organised a taxi for us to pick us up at the airport and we were able to check in early with the baby. We even had a cot and high chair to use. The place was very quiet at night and during the day and felt very secure. Every room had air conditioning as well. A few bits were available to use in the kitchen (oil, sugar, coffee for the machine, salt/pepper, kitchen towels, rubbish bags, ...).
We had a few troubles with the water pressure on day one but Fabrizio came the same evening with a service man and fixed it all in 20 minutes!
The location is not entirely in the centre but public transport is close. The tram takes you directly to the Vatican in 35 minutes. We took the bus to the centre (direct to Trevi Fountain) in 15 minutes during the day when it wasn't busy (takes double at end of day). The Colosseum was 20 minutes by tram and metro whithout waiting times for the tram/metro.
Close to supermarkets and restaurants in the area. There is a great vegan fine dining restaurant 3 minutes walk away. We had a great pizza from Mattarello Parioli.
The only very minor thing to improve would be the size of the mattress for the cot (it is small and leaves large gaps). Our baby was old enough and we could put a few towels into the gaps and it was fine but maybe for a smaller baby this could be a hazard.
Thanks for a great stay!
