I was there end of August during the day.
It was nice but nothing special. It's very quite there, I haven't seen more than 5 people. I think it's very good place to have weddings as they have lots of facilities for this.
The entrance is 5-6 Euro. There is a small cafe on the territory. A lot of benches on which you can sit down or lie down and have rest in the shade of the trees.
I got there by the 2nd bus from the center and walked 15-20 minutes from the last stop of the bus. Not very convenient walking, but it's ok. There is a parking near the garden.
