The stay with Denise was great! Enjoyed it and also enjoyed DC soo much, it was my first time so there was lots to discover!
Right at the beginning I was picked up by a friend of Denise from the bus station, so I didn't have to worry about how to get to the flat :) From there she always could drop me off in the morning at the city centre when she was on her way to work. The flat itself is around 20-40 minutes away from the centre (I guess it depends a bit on the connections you might get), but it was still totally easy to get there, not a big problem at all.
A great help was the map and the metro card that Denise has there for you, perfect for the start and to get around really easy. Loved it :)
And the cat is super cute!
Even at the end when I was going to NY she offered me a ride, cause she and her friends also went there at the same time - and they made sure that I would get all my luggage in the NY metro that evening and helped me to change the line before our ways parted. That was really super nice, since it was already a bit late.
