Konstantin is a fantastic host. Replies quickly, communicates clearly, and is very helpful and thorough.
His place is awesome, you cannot find a better one in Prague. The photos don’t do it justice, it is much better than on the pictures. It is modern, has absolutely everything you may need, spotless clean, and it has the most perfect location. Very easy to explore Prague by public transportation.
One thing to consider if you come by car: the garage has a height limit of 2 m, so if your vehicle is taller, you won’t fit in there.
