We had a lovely stay in Andreas' apartment. Perfectly located between Trastevere, the Vatican and the old town, everything was walking distance while still being away from the hustle and bustle.
Nice bright apartment, very clean and well equipped. Bed was very comfy and we had everything we needed for our stay. Having the little balcony was definetly a plus and we loved having our morning coffee there.
We were checking in late at night and the instructions sent by Andreas were very thorough and easy to follow. Communication throughout our stay was perfect.
The only thing I would point out is that if you're very light sensitive, it's not possible to completely darken the room (thick curtains but no proper shutters). Only a small detail but worth pointing out.
All in all I would highly recommend this apartment and Andreas' services
