The flat is exactly as seen in the photos, very clean and welcoming. We arrived in the flat and gave Marco a call saying we arrived and within minutes someone came to meet us. As I think we were the first staying in the flat he made sure all the keys worked prior to giving them to us which was appreciated. We had some issues with pressure in the 2nd shower on the first day but immediately Marco sent someone around to fix it and had no issues moving forward. Just a heads up, for the iron and hairdryers you needed an adaptor (but I told Marco so he might fix this).
The flat itself is spacious enough for three of us and the beds were comfortable - although the two singles I was told are a little on the tight side. There was some orange juice and water and biscuits left for us which was a nice added touch. It's very clean, good lighting and the air conditioning worked really well in the 32 degree heat.
The area itself isn't an area you'd want to hang out in, but it is very centrally located and within walking distance of most places and right down the street from the train station.
From the CIA airport (25 min) it's €30 and if you're coming back from Trastevere where we spent most of our evenings for dinner and drinks it's about €13 taxi back.
Overall a great stay in Rome and would recommend.
