Simply, great! What you see is what you get.
Very spacious, very clean, many useful amenities, close to 2 metro stations - Vittorio Emanuelle (5 min), Termini (10 min), close to Termini bus and railway station (10 min), close to Termini bus station for both airports, close to 3 supermarkets - Conad (2) and Tuodi.
You can reach Colosseum in a 15-20 min walk and then further away to other touristic attractions.
Great value for tourists!
