We had such a great time staying at Frank's!!
Everything was as described: beautiful flat, lovely neighborhood, located in the center of Amsterdam, literally three steps away from Anne Frank house.
Frank always replied to our emails and, thanks to him, we were able to book his apartment for NYE after many issues :)
Unfortunately, we didn't had the chance to meet him and greet him in person as he was away from Amsterdam during our stay, but he arranged everything so that someone waits for us for our arrival and brings us the keys.
So, it's a warm recommandation we address to anyone who would like to stay at Frank's, do not hesitate, go for it, you will not be disappointed !!!
Next time we come, for sure we will choose this place again and, hopefully, we will have the chance to meet our host ;)

Thanks again,
Thibault & Julie.
