Sonja is a warm and caring person. She clearly loves her city and is super knowledgeable. She did lots of little things to make our stay at her home pleasant and comfortable. Although not part of her listing, she (and her sweet children) treated us to a wonderful breakfast one morning when she knew that we wanted to save time and spend it at the museums! She's really quite awesome.
The location of the house is fantastic. Bang in the middle of the city, at the heart of the university ares, so there's loads of great places to eat/drink. Although the house is a short bus/train ride away, and we had passes, we ended up walking to everywhere the whole time we were there. It's quite an enjoyable neighborhood.
I highly recommend staying here!
