We stayed for four nights. Overall we liked it. The apartment is small but cozy, the kitchen has everything you need for a good breakfast before you hit the streets. And the bathroom is new, clean and functional. The Station and nearly all of the old Town and museums are in walking distance.
Lucyna was very helpful, nice and responded quickly to all questions.
But the streets are louder than expected, because the windows are old and don't have double or triple glass. We could hear normal conversations on the streets with closed windows. So we had to sleep with earplugs.
And the mattress is really really worn out. We were young people with no back issues but we had trouble after sleeping on this mattress. It was no fun and bad sleep. All in all the price is a little high in comparison with the performance.
