Kryštof is a super nice host, communication and check-in were easy and without any problems. We found a map of the public transport system and other helpful flyers on what to see in Prague and how to get around the city in the flat, which was really cool. Wi-Fi and TV worked without any problems, the oven is a bit tricky because the fuse blows if you use to many cooking plates at once. The general cleanliness could have been a little better, but otherwise everything was alright. We mostly took the tram to the city center, which is going every few minutes and takes about 20 min. Tickets are cheap, but the closest ticket machine we found is a few metres away from the station "Koh-i-Noor", so I'd recommend to buy a number of them at once. All in all Kryštofs apartment is a good place to stay and I would choose it again.
