We stayed at Kalina and Walter's flat for 4 days. Their place is located very close to the city center - you can walk everywhere. Anyway there is a good access to public transport.
It's nice and silent area with lots of local cafes and shops nearby. Flat was clean, with all neccessary facilities. Communication with Kalina and Walter was on the highest standart. They were very suppotive and sent us all neccesary information what tourists should know. We were very happy that we chose their flat and would love to reccomend it.
