Christa's place is absolutely perfect and spotless! It is everything she describes and the private bathroom is really clean. You can also wash your clothes and she is very nice and welcoming. Christa even folded my clothes after they were dry!
I really enjoyed my stay there. There is a coffee maker in the room with really good coffee which is a huge plus.
The apartment is less than 5 min from a train station and only a couple of stops from Marienplatz.
I highly recommend staying with her!
