Pros: Good value for money, great cancelation policy, easy check-in, great location, good setup, convenient kitchenette, comfortable bed, friendly hosts, you know that you are supporting a real local family that lives upstairs and not a random company.
Cons: A slight basement smell in the living room, a loud furnace next to the bed, noise from the family walking upstairs, the washing machine is in the same room as the bed so it was very fragrant (laundry detergent smell).
Overall: I had a very nice stay. It is as described. I would recommend it as a base to explore the city. However, not perfect if you're a light sleeper or sensitive to scents.
