The good things: The flat is very nice, and its location is amazing, you can walk to every single place in Rome, all of them were between 10 and 15 minutes, the furthest trip was to the Vatican city which took us around 25 minutes walking. Carrefour express is 3 minutes walk from the flat. the sheets were very clean and nicely organized, towels too.
The bad things: AC and internet, we had very hard time dealing with the heat, the AC was very small and did nothing, and the two fans were not enough to fight the heat of August in Rome. the internet was very slow and kept disconnecting every now and then.
