Like other reviews said, there will be a man (which I think is the management of the church) waiting to show you around the small church.
My interactions with him are pleasant enough, he did not immediately asked me for an entry fee but showed me around and explained the history of the church with a mix of different languages.
The church is beatiful, but small and not very interesting. It does offer some nice views of the river and the surrounding town.
Of course in the end, he inevitably pressured me for a 1€ donation for a barely 2 minutes "tour". But it is up to your discretion to donate whatever amount to not upset him. I donated 20 leke (and told him its 1€), which satisfied him and I'm able to walk away unscathed.
