The property was as described. Its literally a stones throw from the trevi fountain. The double pane windows do a great job. It doesnt totally insulate the noise, but does a darn good job given how busy the streets are.
Some pain points are- the heater is not very effective. So, if you are there in winter, watch out.
Further, there was jus a think throw when the outside temp was around 10 degree celcius. JP offered to get more blankets, but we had to suffer through this for through out our stay as we couldnt co-ordinate to leave the keys.
We had also asked for a crib for our little one and they charged us 10 Euros a night for it. Not sure if AirBnB allows that. We were ok with that. But what was annoying was JP asking us for the money even before checking out. Almost felt like they doubted us to not pay them because we had past history.
Apart from these, the place is good and as advertised.
