During my 10 night stay at the O.C. Hotel, the staff were consistently friendly and helpful. The reception staff were always approachable and gave great advice on transport - They even called taxis for me when I didn't have the number, which was superb. The breakfast waiters did not speak a great deal of English, but this didn't affect my experience, because the communication was clear, pleasant and understandable. The hotel maids were really nice and friendly to talk to when I saw them briefly.
The room was basic and standard, but clean and sound proof! The bed was actually very comfortable (to my surprise) and the air condition was fantastic! I had to turn it down a couple of times in the morning, because I was a little chilly, given it was in fact 34 degrees outside!
The breakfast could have had a bit more variety, the fruit was good, pastries were also very nice, tea and coffee tasted great, but there was no option for a full fry up, only eggs and bacon. Cereal wasn't very varied either and the choice of fruit juice was only Ace juice (which I personally can't stand) and Apricot juice (which was quite nice) but I'd have liked the option of standard orange and apple juices too!
Transport from the hotel to the Metro station was only across the road, a 10-15 minute bus ride. Then from the Metro station you can take a train to the Termini station, which will get you anywhere in Rome.
Overall I had a pleasant experience at the hotel and would definitely stay here again!
