Niko was very kind and always replied quickly, he gave clear instructions of how to enter the building and the apartment. The location is very secure and safe, there are lots of good restaurants nearby and just in general the area is awesome, close to the castle and Charles bridge. The rooms were all clean, although our bedroom lacked a bit of comfort. We couldn't darken the room, and the bed was broken, the walls are pretty thin. Niko provided clean sheets and towels. All together considering the price and the value it was a good experience, I can recommend Niko and his apartments!
