My husband and I stayed at this apartment for 5 nights. Catharina was a wonderful host -- very responsive, gave us good recommendations, and made sure we had everything we needed. The apartment was in a great location -- neighborhood-y feeling yet easy to get to sightseeing areas in downtown and beyond. We had breakfast at the Meyers Bageri on the corner most mornings.
The only downside is, as a few others have mentioned, the ambient noise from the street, the adjacent gate into the apartment complex, and the upstairs neighbors. We did read these reviews, and figured as city dwellers we would be all right, but it was more present at night than we expected, so be advised. We recognize that this is not something under Catherina's control, hence the 5 stars for her and her place.
