What a lucky find! :)
I've been Ondrej's host for four days in january and I really have to admit, that I would come back in any case - no ifs, no buts!
The apartment is very spacious and plain, but also very cozy - simply beautiful! Actually it looks pretty much as you can marvel on the photos on 'airbnb'. Besides the flat's position is fantastic. Just in few minutes by metro and you'll be in the heart of Prague - even if you decide to walk...
Moreover the apartment is absolutely well-resourced. Above all the kitchen's equipment is great. There is nothing at all you're going to miss, so that you even could cook your own Bohemian dumplings... ;)
Ondrej himself is an amazing host. He's very courteous and cordially. And if you've got any questions - no problem! Ondrej helps you wherever he can.
So - don't hesitate and book!
There's no better address in order to explore Czechia's old and wonderful capital than Ondrej's apartment!
