Petr is a really nice host and his apartment is perfect. A lovely space, close to the transport and tourist attractions, price is relative reasonable. Petr respond my message super quick usually short than 3 minutes. This is amazing. He is very helpful and patiently answered all my questions. WiFi is good and check in process is easy. Pert also gives us a lot of local tips which is very helpful. I recommend you guys pick this apartment when you arrive in Prague.
