Nice, safe, quiet neighborhood. Know that you will need to heft your luggage up three flights of stairs on narrow staircases. You will have to share the bathroom with guests from one other bedroom on the same floor.

Be aware as Rosie will indeed tell you when you arrive, that walls are thin and therefore you will not be able to speak on the phone in your room, on the balcony, or on the bench in front of the house. Unfortunately, you may only speak in the living room and your private conversations will be overheard.

Breakfast is at 9 AM only. Unfortunately, the hostess is not flexible on this time, and does not even leave you a piece of fruit. Therefore, if you have a tour where you need to leave even at 8:30, or you want to beat the lines at Anne Frank house, you will miss breakfast.
I had breakfast only once at the house during my four night stay and it was simple continental, nothing to write home about.

For myself, I would not stay here again.
