My partner and me stayed 5 nights in Katerina´s place at the 2nd district. The check-in process was very smooth and friendly and we were able to drop our bags earlier than the regular check-in time. Bernd was an excellent host, explaining us the apartment and walking also outside with us to show us the sourrounding. In a short nice walk one is at Schwedenplatz and at the centre and the next supermarket is 2mins walking away. Though the apartment is on the ground floor, there is no noise coming from outside and the bed is amazing - we both slept very well! As other reviewers mentioned, there is some sound coming from the neighbours upstairs, as you can hear them walking in the upper appartment but I only heard them on 2 nights. Also, the curtains in the sleeping room are a bit thin and let light in, so if one is sensitive to light and want to sleep longer then better bring an eye cover. All in all, we had an excellent and relaxing stay and enjoyed our experience in Katerina´s appartment and we would always come back! Thanks for hosting us!
