We checked in after 22h which costed 20€ extra but Danilo took time to show us the apartment and give some good advice where to eat, shop and how to book online tickets for sightseeing venues to avoid waiting times at the queue. The apartment seemed a bit smaller than on the pictures but we really appreciated the modern design. It was very clean and tidy. Unfortunately the apartment lies on a busy street which made it impossible to sleep with open windows. The house is an architectural jewel in the middle of a lively roman quarter between Piramide Metro Station and Trastevere Train Station. Supermarket 24h, bars, pizzerias all in walking distance. We explored Rom by bike, which was very cool and there is a friendly and good bike rental near Colosseum, www.topbikerental.com. We highly recommend this apartment and it's owner!
