Frank's place is great! You cannot beat the location for exploring Amsterdam. And, the view from the living room is excellent as you look out at the Amstel River and the National Opera and Ballet House.
There is a lot of room in the property. The bathroom is very modern with dual sinks. The only caution before booking Frank's place is that you must climb 3 flights of very steep stairs with narrow treads. If you have difficulty climbing, you might want to book elsewhere.
Frank made check-in very easy. Overall, you can't beat a stay at Frank's place!
