I really apreciated Carsten's kindliness and avaiblity ! He's a great guest, plus, he gives advices and tips to enjoy your trip.
About the flat, it's nice, and with a good situation ! You could go the old city by the close tram station, you have what you need around (restaurants, shops, bakery...).
About facilities, it's perfect, washing machine, wi-fi... ++.
To conclude, Zizkov is a really nice suburb, not so far from the center and where we apreciated to live and enjoyed our holidays. Have a walk around, there is good wiewpoint close to the flat !
Thank you Carsten !
