Greg's place is ideally located for sightseeing in central DC and Georgetown. The apartment is a real home from home and was somewhere we looked forward to getting back to after long days sightseeing. Greg provided a v useful local amenities guide which we used to start our exploration of DuPont Circle, go to the Big Hunt, it's not really a dive bar just a local bar with great beer and good food!
Sadly we didn't get to meet Greg but had regular email communications throughout our stay, this was reassuring as airbnb first timers we weren't quite sure of the protocols, even when to put out the trash for collection!
In all cases Greg responded in a timely manner. We would strongly recommend Greg's place as the ideal base for exploring DC.
