So we stayed at the Residenza Cellini for the first time in November of 2013 and have been back 5 times since then. It was recommended to us by my sister and her in-laws who had both stayed there after reading about it in Rick Steves Italy Guidebook.
We loved (and continue to love) the Italian feel of the place, location, cleanliness but the best part every time is the staff.
Excerpts from my TripAdvisor review after our first stay:
We stayed in a junior suite that had a king sized bed and a twin bed, a small table with two chairs, a desk with a mini-fridge and tv on top of it and a free standing wardrobe with a safe in it. The large bathroom had a toilet, bidet, sink and whirlpool tub/shower combo (the tub/shower came up high on the sides so getting in and out might be tricky if you have mobility issues) and hairdryer. Non junior suites come with stall showers instead of tubs/showers.
The hotel is on the 2nd and 3rd floor with the breakfast room and terrace on the 2nd floor (the entire second floor is a new addition that is set to open in December of 2019).
The lift is one of those old fashioned iron gated things that holds a max of 3 people so be prepared for multiple trips if your party is larger or when you get your luggage in/out. We found it charming!
The location is great. About a 10 minute walk to Termini (Rome's train station) but still far enough away to be quiet. It's just a block of off Via Nazionale so when the weather is good, walking almost everywhere in the Centro Storico is an option.
Updates since that initial review include:
But what really sets the Cellini apart are the owners and staff. Always helpful and ready to accommodate requests, this place has come to feel like our home away from home each time we're in Rome.
I started to think this place was special when we returned a year and a half after our first stay there. At checkout on our first visit, there had been a small issue during our checkout process (no big deal). But when we show up a year and a half later, the same staff member checked us in and mentioned the snafu from our previous stay...so either she remembered us after all that time OR had somehow noted we were return guests and looked up records from our last stay...either way, amazing!
As we prepared to leave from our November 2019 stay, staff arranged a transfer for us to the airport for 5:30am and walked down with us to make sure we identified our ride and got off easily.
When I asked if they had a hotel WhatsApp number that I could text, staff said they didn't but were prepared to give me their own personal number in case I had questions! I declined but gah! Above and beyond every time!
Breakfast is optional - nothing to write home about but certainly convenient if you're not prepared to leave the hotel first thing in the morning.
PS, although we haven't used them, they also have 2 apartments they rent for larger parties
