Markus was very communicative right from the start, always providing us information when we need it within the hour even before we booked his lovely apartment. The apartment itself was wonderful to stay in, in a very central location with interesting views and equipped with some very useful amenities perfect for a group of travellers. The only downside of this stay was the stairs to get up to the apartment - it's a beautiful, older building so there's more stairs than expected for a level 4 apartment.
