Regular visitor to Germany; second visit to Freiburg. We stayed in this apartment for six nights and it is absolutely in a premier location in the heart of the heart of Freiburg's Altstadt. The apartment is in a secure building and very quiet. We met the owner's husband and he was very helpful and kind; owner responds to queries in a timely fashion. Internet is fast and reliable. Very sunny apartment (no view from balcony), big enough for two people.
However, the apartment is not clean, especially bathroom and kitchen. Kitchen area is very small and hard to use, dishes/utensils etc. mismatched, chipped, grimy and old. Bathroom needs deep clean: sink, shelf, toilet, shower and grout were very dirty. Soap and tissues were not provided, and only one roll of toilet paper. Towels are literally the worst I have ever seen and the bed linens were stained - disgusting.
This apartment is in such a good location and it is a great size; I wish I could say nothing but nice things about it. It wouldn't take much to bring it up to a reasonable standard. I would love to come back and to be able to recommend it, but I cannot unless it has been thoroughly deep cleaned and restocked with new towels, linens, basic paper products, etc. I am very happy to stay in older rentals, but cleanliness is not negotiable.
