We loved our stay in Trastevere and staying in Alberto's apartment was fabulous. Everything is as stated - comfortable beds and loungeroom, kitchen & bathroom facilities all excellent. Communication was great and any queries or requests were promptly dealt with. Highly recommend!
PS: If you are visiting Trastevere, be aware that most locations can be a bit noisy at night due to the bars and restaurants which are everywhere, but remember, that is Roma!
