The room is the same as shown in the description. There is a bus from Roma termini which help me reach Dario's place easily even with the big luggage. Colosseo is within walking distance from Dario's place and I think it is very nice! Dario is very nice host and gave some advice on good restaurant so don't hesitate to ask!
Last but not least, there is a maid to clean the place few times a week (at least 2 times within 5 days), which feel like staying in hotel but with very good price. So, I recommend people visiting rome to stay with Dario!
