Thanks to Denise, Peter and her assistand Glenn I had an amazing stay in Washington. They were very friendly and I enjoyed chatting with them about Germany, the US and so on. My friend and I were also very grateful for the pick-up service from / to Washington Union Station. Last but not least, the room was clean, the bed was super-comfy and even the cranky cat won my heart :-)
If I had the chance to go back to Washington I'd definitely stay at Denise's once again.
