First to get the only not so good thing out of the way:
THERE IS ONLY STREET PARKING
That being said, we found a spot right in front of the entrance, so it was not a problem.
The staff was very helpful and friendly.
The room was clean and the AC worked very well.
Get the offered breakfast, it’s cheap, there is a lot of options, and the crepes (pancakes in Bulgaria) were delicious, especially with honey.
There are a couple of Restaurants along the river that are within very short walking distance.
My wife and I would stay there again.
