The park situation ist difficult. Also that there is no possibility to reach the house by car, which means that you have to carry everything to the house. Finding a free parking spot was a daily challenge ... the flat itself was nice and clean. The fridge was broke but the hosts reacted fast and very friendly ans gave us the keys to another apartment for using the fridge there. Check-in and out were perfect. Also the communication. Within minutes we got answer.
So, all in all, if you don't have a car it's a great location within the centre and close to the lake. For us climbers - using the car every day - it was a bit laborious. =)
