Marek's place was just great, you absolutely can't beat the value for money - location was absolutely amazing. The bathroom didn't bother us at all. The only thing that might bother you is the noise. Quite early in the morning (7AM-ish) it was pretty noisy in the small street that was right by the building, so keep that in mind if you want to sleep in while on vacation. I'd rather have some noise but stay in the city center.
