Perfect location. In the heart of everything and right next door to the Pantheon. Easy walking (< 25mins) to all other tourist destinations without the need for transport including Trevi Fountain, Spanish Steps, the Colosseum and Forum, the Vatican and St Peters, Villa Borghese and more. If you need a taxi there is a taxi rank right outside the Pantheon. 30 Euro fixed fare from here to Ciampino Airport. I think I was overcharged from Airport into Rome because I didnt know about fixed fare on my arrival or maybe it doesnt work the other way?
Lots of nearby supermarkets for provisions, sandwich shops for cheap lunch and numerous restaurants all nearby for the evening - see Trip Advisor for these. Too many to mention but one recommended by host ( Da Pietro Al Pantheon, Via Dei Pastini) was excellent, friendly and good value . Lots ATM machines in the Pantheon vicinity.
Beautifully clean. Nicely decorated with period furniture. Great accommodation for three (one double bedroom and one single bedroom, each with ensuite) with all required amenities including kitchen and laundry facilities if you need them.
AC is present but was unable to keep the bedrooms totally comfortable during our visit which coincided with a Rome heatwave/drought in July/August 2017. Additional bedroom fans did help a little. It is acknowledged that weather conditions were extreme during our visit.
On balance, fairly priced and reassuringly clean for such a prime location. More advantages than disadvantages!
