The room was nicely prepared for us. Niko met us in front of the building, explained everything, showed stuff and gave some advices how to get to the city, where to leave the car. We were sharing apartment with other people, who were living in other rooms. Place is around half an hour of walk from old town, but there is tram and metro going near by for easier connection.
We only had one tiny concern and another tiny problem. Concern is that in the apartment at once can live quite a bit of people, and for shower there is only one boiler of water. It is quite possible to run into situation where you will have to use cold water if others used the shower before (we avoided this situation by showering after coming back during night time). And the problem is, which, I hope, will be fixed, is that one mattress in the bed had a big hollow in the middle, so my friend did not sleep that well, since part of her back was in that hollow all night.
Otherwise, the room and apartment met our needs, since we only wanted to sleep over in Prague. Price was friendly, we had blankets, pillows and towels in the room, check in and check out was not complicated. Very thanks for Niko! And hope to visit again!
