Marek's place is wonderful! He met me at check in and went over the whole city--how to get around, where to go, etc. he has everything written out on a map hung on the bedroom wall and his overview was so helpful. The apartment is exactly as it looks in the pictures. Very clean and comfortable, located in a great place. Marek was always available by text if we needed him and he lives next door, so check in and check out are very easy. He has every resource a traveler could want. I highly recommend staying in his place if you visit Prague!
