Pros: clean, organized, kind staff (they have borrowed cutlery and dishes), near the station (not very near), enough space, very nice bathroom and shower, fridge, nice neightbourhood, near the metro/bus/market.
Cons: no elevators (with a high stair), noisy, both air conditioning and heating were not working, breakfast available for 4 euros each person, but with very limited options (tea or milk, one croissant and a yogurt).
Although considering costs and benefits it was a nice and confortable hotel to stay when in Rome.
