Mark's place was amazing! His communication was stellar! The only things to be aware of are that this is not a quiet location as the garbage trucks come early and are quite loud. The parking situation is quite a challenge but Mark is very up front about that and gave amazing options for garages near by. If you have heavy luggage it can be a challenge transporting to and from as well as up the stairs to the units. The space however is impeccable and would recommend it to anyone headed to DC!!!
