I slept very well at Nerva. The bed was very comfortable. Location is great, literally just a step out of Cavour metro station and a few minutes walk from archeological venues and shops. There was no noise from the street and room and bathroom were very clean. It is a great value for money. I would give 5 stars but Host never responded to messages on Airbnb which was quite stressful as I wouldn’t be able to make calls from my cell phone. Hopefully I was traveling with friends and I managed to call Host from a friend’s phone and get check in instructions. Quite stressful experience though.
