Staying in Michal's place was just what we needed. It is perfect for a family. has a spacious kids room, with a lot of toys. Located right next to the Metro and has an elevator which is fantastic considering the amount of stairs you'd have to climb and go down to the metro with a stroller. It is a bit loud at nights and sometimes doesn't feel quite safe, but never had any trouble and people were quite nice.
Also, there is a highly recommended Boulangerie right next to the apartment.
Michal was very communicative, helped us with any question we had, and the apartment was very clean.
overall, highly recommended!
