The location is simply perfect. Right next to Panteon, walking distance from piazza Navona and fontana di trevi.
The appartment is spacious and clean.
Communication with Valeriano was easy and he let us stay longer on departure cause our flight was leaving late.
The only problem (of which he informed us on arrival) is that there was a problem with the water pressure in the building and so no warm water in one of the bathrooms. In the other, we had to re start the boiler every time before a shower which was inconvenient.
