The apartment is great and nicely furnished, near to the city centre. You need 15 minutes to the Dlouhaa street if you walk and just around 5 if you go by tram. The station is just behind the corner. Lukas is very nice host, he told us where to go in the city, where to change the money and which restaurants are the best. We would definitely come back to Lukas's place if we visit Prague again.
