excellent flat for great value- close to airport, 5-7 min walk to metro and tram (Petřiny) and grocery store. Nice big open studio with big working table (if that's what you need), well-equipped modern kitchen, modern bathroom with tub and washer, good internet. On ground floor near path where people frequently walk with dogs but very safe and quiet. Plus Petra is a very responsive host!!
Highly recommended, especially​ if you're in Prague for an extended period of time and want relatively quick access both to central Prague and to airport.
