I loved my stay at Kim's place. I was in DC for a conference, and although it seemed a little way out looking on the map, the metro station is a 5-10min walk away and easy to navigate, and I could get to the stop I needed easily. The flat was very cosy and warm (which was welcome, given the dropping temperatures in DC!); and the bed was extremely comfy which I always find helps when you're staying away from home (and jet-lagged). There's also a very powerful and hot shower, which helped to get me out of bed in a morning. The flat is small but perfectly formed, and Kim obviously takes a lot of care over it. The facilities for making your own food are minimal, but completely as expected (as per the advertisement), and was perfect for me as there were a lot of conference dinners.
All in all I had a very comfortable stay, and I'd recommend this place to anyone that thinks it fits their trip criteria. Kim was welcoming and flexible and easy to get hold of if needed. Thanks Kim!
