When you go down 'Kliment Ohridski' street (to the lake) you should see at some moment a square with both a fountain and a massive tree (old plane tree).
Go down 20 meters.
On your right there is tiny street next to 'LUNA'-open bar and pizza restaurant and 'SKOVIN'- wine shop.Take it (double curved, paved street).
After 100 meters turn left (opposite side to the church).
This is number 26 on the left side.
