We had a fantastic experience at Polash's BnB, it was clean, affordable and Polash himself was very helpful and kind to make sure we had a good stay. Bed was comfortable and we slept well here - very quiet at night which is a big plus. Price seems very good for Rome in peak season as well (July).
The neighbourhood is quiet and safe, full of embassies, which even means increased security.

We arrived by car and was able to park in the street for free (look for the white stripes at the end of the street!!) for our entire stay. Another bonus is that Polash's BnB is outside the limited traffic area - be sure to read about this if you visit Rome by car.

As an additional lovely gesture by Polash, we were able to forget a number of clothing articles, which Polash was so kind to ship to our home address! Thank you again!

So overall, for an affordable, nice, quiet stay in Rome, very centrally located, do not hesitate to stay with Polash.
