Normally, I don't comment on hotels, but I'll make an exception here.
I, too, love the Hotel Lancelot in Rome. I stayed there in September 2022 as part of a Rick Steves seven-day Rome tour. Of the probably 75 hotels, B&Bs and hostels I've stayed in over 15 trips to Europe dating to 1993, the Lancelot is in my top 5.
The Lancelot is like a European hotel of yore: The management and staff are genuinely like family, the atmosphere is relaxed and homey, the bar and dining room are comfortable and the patio in back is a hidden gem.
I have a fun memory: The closed driveway in front of the hotel has an old Fiat on display as a kind of attraction. I'm 6 feet, 2 inches tall, and the old Fiat looks like a Matchbox car. Somehow I managed to squeeze into it and have a photo of me snapped. I look like Fred Flintstone hanging out of his stone age car. It's one of my favorite photos ever.
