The icon painter’s studio is easy to find: start from Tsarevets square (right next to the fortress) and go in the direction of the town centre along the right one-way street. 50 metres up the street, on the left-hand side, you can see the signboard with the spring where the doves gather. Just above one can see the Cathedral of the Nativity of Virgin Mary.
To find the studio even easier, have a look at google maps:
