Alex&Natalia are very nice hosts. Great communication! But they are an apartment operator only. The real owner of the apartment lives in another apartment in the same building - unfriendly and gloomy man.
The apartment is on the 4th floor of a five floor building with a non-working lift.
WiFi didn't work but Alex&Natalia solved this problem next day (on Saturday). Thank you very much for this.
The windows are very old and decrepit. Be careful, the windows are open in this apartment when you turn a handle at 6 o'clock (not 3 o'clock as everywhere). I've tried to open it at 3 o'clock and as a result the glass has felt out the frame and crashed on the floor.
The floor is rather cold as it is covered with glaze all over the apartment. So, do not forget your slippers.
This apartment is in the center of Prague (5-7 mins from metro station I.P.Pavlova, 10-15 mins from Waclavska namesti).
