We were so happy to have found Relais Conte di Cavour. It's a very small hotel, more like an apartment divided into rooms, but well fitted out and comfortable.The staff were extremely helpful and friendly, and stayed back late to let us in due to severe train delays on our arrival day. The bed was one of the most comfortable in a 4-week holiday around Europe and whilst the lighting is kind of kitschy (green lights in shower, blue light chandelier in bedroom), it's also kind of cool. The location is very convenient to the Metro, buses and several interesting sights, as well as being very close to the main train station without feeling like it's in a dodgy part of town. Great value and highly recommended compared to other hotels on offer in Rome.
