I didn't see much of Greg since I was at an event for most of my stay. However I will say that I got a very warm welcome from him and his lovely girlfriend and nothing was too much trouble. One night of my stay, when Greg came home later than I did, he crept into the apartment so as not to wake me (I was already awake) which I thought was really considerate.
The apartment itself is extremely nice, and in a great location. Safe area to walk around in after dark and within easy, quick walking distance of the L Line, so only minutes away from Manhattan. Thanks for hosting me, Greg!
