Stairway to Heaven is exactly that. The accommodation was immaculate and well presented with all the facilities you would need - sanitary products were provided along with things like shampoo. These added extras were appreciated!
The stairs are very steep but we only struggled when taking the cases up - you get used to them!
Location is fab, there is a local food market on the street outside everyday except Sunday and bought a lot of food and snacks from there. There are plenty surrounding food places for breakfast, lunch and dinner as well as supermarkets. There are no cooking facilities but plates and cutlery etc were provided.
The tram stop that takes you into central Amsterdam in a matter of minutes is a 2 minute walk from the apartment. Vondelpark park is a couple of streets away too!
There is a local cheap bike hire place in the street opposite which charges 10€ a day for bikes if you prefer this to trams - this seemed cheaper by far than others we found.
I’d recommend The Breakfast club just up the street as well as sampling local food from the market.
Overall we loved our stay and will be back for sure!
