4 for us for 4 nights. The apartment was clean, spacious, airy...eclectically decorated reflecting the artistic profession of Marek and Eva. They and Albert their son settled me in (I arrived ahead of the rest) and explained everything. The apartment itself is in a v nice area, quiet and well withing walking distance of old town and many restaurants / bars. And yes, v thoughtfully there was extension cord with multiple outlets for charging the multiple gadgets we all now travel with!
