Marcel and Mildred place is just wonderful. The terrace is amazing.
Position is 10 to 15 minutes walking from Dam Square, which is good because is outside the city center mess but still close to everything.
Although we didn't meet Marcel and Mildred they were really nice and communication was easy and fast.
We were welcomed by a friend with a white wine bottle which is always nice.
We recommend this place to every one coming to Amsterdam!!
