My partner and I had a great stay at Petra's place. It's right around the corner from the Albert Cuyp Market so we were able to go there a few times during our stay to browse items or to pick up some olives, cheese, brownies or other snacks. The apartment is easy walking distance to public transportation and also accessible by foot to the center of town if you're up for a 20 -25 min. walk. The neighborhood has plenty of restaurants and cafes including a couple of really good Indian restaurants just a couple of blocks away.
The apartment itself was just as it appears in the photos. We found it very cozy and comfortable, with a great view out the window. There's a small kitchenette and Petra provided a hotplate, toaster, tea kettle and coffee maker, so we were able to have our breakfasts in the apartment as well as heat up some leftovers. There was also coffee, tea bags and some spices as well as plenty of towels, extra blankets, etc. As is mentioned in the description and other reviews, the stairs are very narrow and steep - by the end of our stay we were quite used to them, but it's best if you have either small luggage or a backpack and don't have mobility issues.
