I live in Amsterdam myself, but needed a few nights in a hotel. I found Edwins place, and thought it was VERY cheap for the location.
I read that Edwin was a happy, friendly guy, and still I was surprised by how friendly he is!
And the location is really amazing. When you are a tourist visiting Amsterdam, this is a really great spot! His house is in a street between Reguliersdwarsstraat ("Amsterdams most famous gay street" and the famous flower marked. Area is full of restaurants and bars, a guaranteed fun time awaiting right at your doorstep. Close to Leidseplein, Rembrandsplein, Dam Square. All the shopping you can wish for, short way home with your bags. You will be living smack in the middle of all the good stuff. :-)
It goes without saying that when you stay in such a lively spot you need a pair of earplugs for when you want to go to sleep.
Comfy bed, shared bathroom, great way to see how the Amsterdammers live, while climbing up the steep stairs. Do like the locals.
I would recommend Edwins place to anybody!
