That apartment is the best choice for those who would like to spend some days in Rome. It is really close to all the sightseings and metro. The interior is quite nice. If you searching for apartment with microwave or washing machine, this is not. But for me it was OK. There are also a little fridge, safe, air condition and heater in the place. The beds are really comfortable, so you will sleep like a baby after a long day in Rome :)
The most important thing for me is that Manuel is a really great man! He is very communicable. It was my pleasure to meet him. He will definitely help you with any problems you may have.
