This place is very nice and convenient, and we would recommend it to anybody. The location simply cannot be improved: a few blocks to campus, in a peaceful and pretty street very close to where the action is (Wisconsin Ave and M Street are a block away). Unless proximity to metro is key for you (and this is a weakness about Georgetown, not about the apartment), it is hard to find a better location than this. Plenty of bus lines go through a block away.
Samia is very nice and practical. We needed her help a couple of times (getting in the place very late because the flight was very late; getting internet fixed after a storm) and she was there. Her post was clear and very accurate.
The place itself is ample, one of those long and narrow apartments typical of the houses in that area. Living room and kitchen are perfectly fine, both bedrooms comfortably fit two people and are appealing. Another host would have claimed "sleeps 6" given its huge size. Having washer and dryer in the apartment is really convenient if one is staying, like we were, for two weeks or more. The only room in the house that is not at the level of the rest is the bathroom, which is clean but a bit small and cramped.
It is a great place and we are very grateful to Samia.
