We had a wonderful appartment - very clean, spacious and comfortable, with a small kitchenette; loved how quiet the place was and a nice terrace, where you can have a breakfast in the garden; breakfast was the same every day and quite basic.
The hotel is very small, converted from two houses and gives the feeling of staying at your friends' home while you are at the center of Belgrade with all tourist spots 5-10 min walk away. Everyone in the hotel was very friendly and helpful while we stayed there.
I hope they will fix wi-fi as it was unpredictably on and off while we stayed, but they had works done for it.
