I have been going to Ace nails it seems like forever! I think it has been since around 1990! They had a location on 17th street I believe before they moved to this newer location (still in Dupont Circle). I think they do a terrific job - always professional, the place is always clean - including all the instruments - it doesn't smell awful like a lot of nail salons do - in fact, no chemical smell at all ever - and while the staff changes somewhat - the same woman that runs the place - seems to have been there for at least as long as I have been going there. The prices have maybe gone up one or two dollars and are extremely reasonable. I love their hot towels in the winter and how nice everyone is whenever I go. It feels like my own neighborhood cheers bar (without the booze). I've moved in and out of the City and even across country but I always always always go back to Ace Nail.
