Perfect communication with the host, which meets you personally, also give some advice about places/restaurants to visit. Perfect localisation, just 15 min walk to Colosseo, close to the metro Vittorio Emanuele and Termini station. For the first sight the place seems to be dark because the windows overlooked the yard. But actually due to the hot weather in Rome, that appeared to be great plus - there wasn’t too hot inside. Functional and tidy, with all needed for even a longer stay.
There is no option for self check in, if you arrive later than 11 pm. you should pay extra fee.
