I spent 5 days (and 4 nights) in Rome at Luca´s apartment. I had an overall very good experience staying there. Here are the pros and cons.

pros:
- modern studio with room for up to four persons
- the apartment and bathroom were thoroughly cleaned before we came and after we left
- small kitchen with everything you need
- washing machine available
- AC
- WLAN
- closely located to the Forum Romanum, Colosseum and Metro Circus Maximus (10-15min walk)
- price

cons:
- guests being > 1,90m or rather "well-build" persons might have problems using the shower (this fact did not affect me. I am 1,78m and well muscled), so you might keep that in mind if you are tall or carry so more weight.

- I was confused with airbnb´s address. It said Via di Leonardo no- 2 but the house no. was 12
