Marco is a great host. The check-in was easy and efficient as well as all communication with the host. The flat is nice and comfortable, and the location is great: just 5 min by foot from the metro or 1 min from the bus stop, so you can easily be on the train station or in the historical center of Rome in less than 30 minutes. The only thing that you should bear in mind is that the boiler in the bathroom is quite small, so that it might be not enough hot water for two persons taking a shower one after another or even for one person who needs to rinse hair twice (e.g. while using not only a shampoo, but also a conditioner/mask).
