My daughter and I stayed for seven nights at Petra's apartment.
Everything was as described. Petra meet us upon arrival. We had no issues with unit or location.
There was only a mild inconvenience with some construction just outside the inner entry way. Petra did alert us to this.
Please pay attention to the exterior access to the toilet, the shower tub arrangement, the loft bed access, lack of privacy between bathing and sleeping quarters.
Again this is all mentioned and if you aware and agreeable then Petra's location can be recommended.
While I was pleased with the location if I was to return to Prague I would probably seek an arrangement with higher comfort level.
