We stayed in Robinson hotel for 6 nights. The location was great-only few minutes from Termini station, which is the central station in Rome, and from which we could have all the kinds of transportation (bus, metro ,train). This area is also full of fast food restaurants, which was very convenient.
The breakfast was very good and rich- bread, cheese, cakes, hot croissants, cookies, cereals, fruits, coffee and tea.
The staff was also very(!) friendly- They helped us in every question, and recommended us nice places to go.
The rooms were very basic- In the standard room, where we stayed for the last 3 nights, the toilet and the bath were in the middle of the room (there was no separated room for it), which was very unconvenient and definitely lacks the private feeling.
We also stayed in the Delux room for 3 nights, which was very small and crowded. We couldn't leave our bags open, because there wasn't enough room for us and for the bags in the same time! I also have to mention that everyday the rooms were cleaned including new towels were added.
This hotel is good for people who want to tour rome, not to stay in the hotel. We were that kind of people, so for us the hotel was quite good and we were satisfied.
