I had a very nice stay at Dina-Perla Lodges. Dina-Perla was welcoming and extremely clear on how everything works. The place, although 200 years old, is spotless and is kept is a pristine condition. There is a classy common area with a piano, a guitar, playing cards and plenty of room. I'm a violinist and I was encouraged to practice in there. The kitchen is very clean although there is a no-cooking policy (utensils and the fridge are available for guests to use).
There are two toilets and a spacious shared bathroom with a really nice shower, all of which are spotless.
The bedroom I got has a twin bed and a desk. Two very comfortable comforters were provided and the bed is right next to the radiator, so the cold wasn't a problem at all. The traffic noise can be heard through the windows, but it wasn't too disturbing and a pair of noise cancelling earbuds made it a non issue.
Overall, it was a great experience and I'd love to stay there again next time I'm in Amsterdam!
