I took my partner to Rome for the weekend for his birthday and stayed in Monica's place for the trip. I booked it a little last minute and her quick response was excellent. I booked mainly for the roof terrace which looked almost like pictured, if a little unloved, and for the location. There were a couple of things to note however;
Even though wifi is offered, there is no connection. Myself and my partner assumed that the device was a booster rather than a wifi box, that coupled with being on the 9th floor, it was never going to happen. We managed to get a faint connection on the first night but after that it was gone. I recommend sussing out Internet cafes and wifi hotspots for your trip.
During our stay we had to turn the water boiler on before we could access hot water. Which ofcourse is fine if a little outdated. It did however take over an hour to heat up and the shower itself had 0 pressure so was like washing under light rain.
The last thing to mention is the location. You are around a 10 minute walk from Trastevere Main station which is fab if you are coming in from Fiumincio airport (30 mins away). There are bus stops at the station and tram links close to the apartment as well. It does however take you around 20 minutes (by tram) to get you to the hubbub of Rome itself and I would even recommend taking a tram to the centre of trastevere as that is quite a walk away. Even though there are plenty of walkable transport links, it would be nice to be a little more central.
Overall we had a nice stay. The bedroom is large and the bed very comfy. The terrace is great to eat out on and you have the basics of what you need. Make sure you organise your check in requirments well in advance. Monica and her nephew are lovely and I would stay in her place again.
