We can highly recommend this place.
Location is excellent - 5 minutes walking from the coliseum and the Roman forum (which in my opinion is even more impressive), 15 minutes from the main train station.
The room is not luxurious but was very clean and neat and includes everything you need (air conditioning, fresh towels, good bathroom and shower).
The hosts were amazingly kind and very flexible with the check in and check out times and even gave us some advice on what is worth seeing in the area and how to get there, including a map.
Last but not least - breakfast is included in a cozy nearby coffee place.
