We had a wonderful time @ Marshall and Eva's place. The apartment is really nice and there is everything you need; it's a perfect home away from home.
For us there would be 3 reasons to stay there again:
1: Marshall and Eva's (they were so friendly, gave us some good restaurants addresses, places to go, Jazz clubs...)
2: The apartment (we would love to come back during summer and sit on the terasse. This was not possible this time...rain...cold)
3: Washington (nice town and an interesting destination for foodies)
