Alex and Natalie we're both extremely nice and waited for us very late despite train delays that prevented us from arriving on time. The apartment is very cute and comfortable and in a great location. We had a little trouble with the heater turning itself on which was not very fun in July, but Alex responded immediately and managed to turn it off while we were out exploring the city - very attentive and nice hosts who clearly prioritize their guests comfort. We definitely recommend staying at their apartment.
