First of all, the location of the apartment is very good. A 5 minute walk to the next subway station to Manhattan makes it pretty convenient. Also, if you need small groceries or food in general, there are lots of (fast food) restaurants and supermarkets around. The host(s) are very friendly and are eager to help. Plus, the communication is direct and straightforward.
However, you should be aware of pets (dog & cat) which lose hair/fur and some spots were dusty like in e.g. the bathroom or our rented room, but if you are not allergic, just staying for a couple of days or do not care about that, then it's not a big deal. Additionally, the walls in the building are not that soundproof so that you can hear e.g. the TV from the neighbors when it's rather quiet in the evening.
All in all, it was a nice stay and it is good value for money.
