We had to organize the coming of 20 persons. The booking office executive made us trouble few days before the arrival of all the guests. She was horrible at phone. Then, arriving at the hotel reception, the staff was unwelcoming, unhelpful and unorganized. Fortunately I arrived before guests. They wanted to make some people pay for the services we had already pre-paid. They were aggressive with the guests and some of them had to negociate to enter the dining room!!
The dinner organisazed there was extermely expensive compared to the service we received and the quality of the meal! 39€ per person for eating uncooked pasta, few vegetables with cold meat and a dessert without taste! 35€ for the dinner buffet the other nights was also too much.
The rooms: old TV from the 90s, uncomfortable bed and pillows, no bottle of water in the room and a heating which make noise all night long (had to put it off in the night and the wake_up was cold!).
Only positive: breakfast + quite good localisation

Poor dirty noisy room. They advertise free Wi-Fi all over the hotel but charged me for each connection. Refused to take it off my bill. Said I had to ask at check in for Wi-FI. I will not be staying here again.

We were told that this would be a an excellent night's sleep before our long travel home. The room was 140 Euros, the beds were hard as rocks, the room was too hot even with the cool weather, and the AC would not work. Even leaving the window open all night we remained uncomfortably hot. When checking out, I was not asked about the stay, and tried to communicate the problems, but was ignored. The room was rented for two, but only one large towel was given When we tried to communicate with the front desk, no one picked up. The only highlight was the breakfast, which was very well done. I would not recommend this hotel based on the cost. The Youth Hostels in which we stayed had better beds.

The Leonardo da Vinci is on a quiet street. It is one block from a main shopping street (Via de Coll di Rienzo), and about a 15 minute walk to the Vatican. My bed was comfortable. They had free wifi, but you needed a new code each day. The breakfast was very good. I was there as part of a tour group, so I am not sure how much we paid for the rooms.
