Anastasiya's apartment is very nice. It's spotlessly clean and all amenities are very new. However, be aware that the apartment is smaller than it appears on the photos (although large enough). Also, any serieus cooking is very difficult, as the kitchen is very small, there is only one stove pit and there is't very much equipment to prepare food with. We managed to prepare some simple meals and the equipment is more than sufficient for breakfast, but any large dinner is going to be a challenge.
Finally, be aware of the checkout time! We thought 9 was quite early.
Nonetheless, we had a pleasant stay at this apartment and would, keeping the above comments in mind, recommend it for anyone's stay in Prague.
