Hristo is a nice, cheerful young man. My wife and I stayed at his place when we visited Rome. He was very welcoming and provide us Rome City Map. We walked about 15-20 minutes to his apartment from Roma termini station and it is very close to Colosseum which is about 10-15 min by walk. Manzoni - Metro station is just nearby. We took the metro from Manzoni station to Ottaviano station to visit the Vatican city.
The room is very nice and beautiful, everything was the same as described in the site. This room has a private bathroom inside and it is clean and tidy.
Definitely I would stay in his apartment when we visit Rome next time.
We recommend Hristo and his apartment.
