The place was okay. A bit dark and cold, and smelled a lot of cigarette smoke (if this bothers you at all, this is not the place to stay) The room had a nice door to the outside. Although this place was fine for me, I would say that if you're used to cleaner and newer places with more privacy (the walls were thin and noise traveled) this is not for you. The apartment is, however, pleasingly close to Westerpark, which was nice to sit in and watch the birds.
Both hosts speak great English, helpful if you're not bi-lingual and English is your language.
No major issues, just make note if you're sensitive to smell.
