The Richmond Hill Hotel is very nice. The Georgian Suite we booked is pretty and a good size. We just had an excellent meal in the hotel restaurant. Based on a few hours stay, I'd recommend it if you want to stay in the area.
Strawberry Hill (Horace Walpole's house) is well worth a visit.
Car services (Uber, FreeNow and Bolt) in the area are terrible, but that's not the hotel's fault.
