We stayed at park dei massimi for 5 nights while we were in Rome, we were very impressed from the moment we arrived, the staff were extremely friendly and helpful, we felt very welcome their the whole time.
The restaurant was fantastic and the food delicious, with plenty of options.
They provide a shuttle service from the hotel to the Vatican city or the metro station and an evening pick up service which was very useful.
If i have to complain about anything, the wifi was a bit patchy in the rooms and the bed was a bit firmer than we are used to.
overall we would fully recommend Park dei massimi for a pleasant stay in RomeMore
