My partner and myself recently stayed at Hotel Relais dei Papi for three nights. The hotel was conveniently situated close to the Vatican and other tourist attractions.
We found the standard of the room to be very good for what we paid and the staff were friendly and approachable. The bed however was very hard. Unfortunately, we were located on the fourth floor close to reception and as a result of the paper thin walls we heard everything - best to avoid if given the choice. The breakfast area is small and the breakfast in comparison to other European hotels we have stayed in, leaves alot to be desired.
Overall, we were pleased with our choice of hotel for staying in Rome, and would recommend to our family and friends.
