We mostly interacted with Artur, Helena's husband. He was incredibly helpful and hospitable. He gave us tips for what to see and where to eat and everything! We had some trouble with the heater and they were very prompt in responding to us, which kept us warm and cozy for our long weekend. The only setback is that the apartment seems really newly furnished so some of the drawers etc. aren't very sturdy... maybe a better place for a few day rather than a longer stay. Very sweet apartment and great experience overall.
