Absolutely loved this place!
It's entirely decorated in old furniture, gorgeous. And the art in it is spectacular!
The ground floor has new art that is for sale and the upper floor has old art that is there just for exposition. Both are lovely to see, although I think the old art is still better.
The staff is very nice and can provide good explanation if needed.
At the end, they give you a a little postcard (which you can choose from a few different ones) which a painting printed on it and you can keep it for yourself or send it to your loved ones at the poste (which isn't too far away).
The price, I believe, is 6lev (3€ more or less) per person but students only pay 3.
If you like art and are in Plovdiv I would definitely recommend!
