The place is very nice located, at around 15 minutes from the central station (12 min by tram, then 3min walking). It is very relaxing arrive at Sandras place after a busy day in Amsterdam. It is very quite, very comfortable and the balcony is great for watching the stars in the night.
The only thing to consider is that there is no kitchen, only a water heater to make some coffee. A great place to stay, we would definitely recommend it!
