I love this place because they start serving breakfast at 6:30. At that time of the day you find yourself in an uncrowded, classy environment of one of Amsterdam’s best hotels. Their 30 something euro breakfast buffet includes unlimited coffee any way you like, fresh fruit juices and is a great spot…
They have a great G&T Bar in every flavour imaginable inside the hotel. Open for visitors. You will have to go through the lobby to get in.
It isn't cheap but the building is worth a visit. Just have a coffee or glas of wine at the bar or visit the shops inside.
