Hunan is an nice guy! He not only waited for us to check in until 23:20 as we had a delay with our flight, but also he let us check out 2 hours later than usual. We really appreciated such flexibility and his friendly approach.
The location is close to metro and about 15 min walk from the Colosseum. The neighbourhood itself is convenient for travellers on a budget, though the whole area around Termini is among the things we least enjoyed in Rome.
The room is fine, we spent there 5 nights and it was relatively clean and neat.
I will overall recommend Hunan as a great host.
