I stayed in Ruben's apartment for 3 nights as a solo female traveler in Amsterdam. De Pijp is a small neighborhood outside the city center that is completely safe. Ruben greeted me at the door and made sure I had everything I need, then didn't bother me for the rest of my trip. You share the floor and bathroom with another guest/couple who is also renting. This wasn't too much of a problem, as I didn't run into them during my stay. The bed is incredibly large and comfortable, and the room is very airy and spacious. Exactly as pictured - clean and classy. Two things I would point out - it happened to be 90 degrees during my stay at the end of September, so I had to sleep with the windows open. Unfortunately, there was quite a bit of noise outside the room throughout the night (as late as 2 AM.) This wasn't a problem once the windows are closed, so it totally depends on when you visit. Also want to note that De Pijp was not as central as I would have liked, although this apartment really was a great deal and probably worth the trade off.
