Apartment is very much as the photos show it, and in a fantastic location - steps from the main square in Trastevere, yet very quiet at night - it's a mainly pedestrianised area, so the usual annoyance from scooters wasn't an issue. Pietro was very responsive and helpful, we had an issue with the heating and it was sorted immediately, and he organised a transfer for us from the airport, which was very much appreciated.
The bathroom could have been cleaner, I mentioned this to the host and there was an offer to come an clean it again but we declined. There was plenty of hot water and the heating/ aircon worked well (it was a little chilly when we were there) and the roof terrace was lovely, we only got to sit on it one day but it would be glorious in the summer.
My only real negative would be that the furniture could be upgraded a little, the sofa in the living room was not particularly comfortable and there was only one chair which was rattan, there were three of us so we managed fine but a larger group might struggle if the roof terrace wasn't an option for the evenings/ relaxing. Also the main double bed was not very comfortable - too soft. Finally, the smallest window in the second bedroom didn't have a shutter, which meant that it couldn't be blacked out in the evening - we improvised so that my daughter wasn't disturbed by the light but some kind of blind would be a welcome addition.
Some minor upgrading and attention to detail and this would be five star - nevertheless we enjoyed our stay and would recommend.
