All complaints about the smell were caused by me, since I was staying here with guinea pigs from august to October and I wasn't able to keep their cage smell under control.
I have no idea why this place is priced so low, I stayed here for 4 months and the location is perfect for interns, the house is consistently clean, the walls are sound-proof, the neighborhood is safe and quiet, and it comes with all the appliances you need for the long term. Aside from the broken dishwasher (as of november 2019), it's nothing less than the middle-class life, plain and simple.
