Adam&Stepan are very kind and helpful hosts. The appartment (we had booked both the red and blue unit) is huge (perfect for large groups) and beautifully designed. It has a nice atmosphere, the rooms were clean and there even were some welcome drinks in the fridge. The kitchen has everything needed for cooking and the bathrooms are very fancy.
Long story short: We would love to come back. :)
Oh and they serve delicious coffee at their café nearby!
