This is the first time I have ever been disappointed at a stay.
1. Check-in: it was not clear until my check-in date approached that I had to obtain the keys at a sketchy hostel which is a 10-min walk from the flat.
2. The flat itself is small and outdated, which is fine, but it reeked of mildew. We tried to minimize our time inside because of this.
3. We were not given enough paper product.
