Short hint for the value of the key service_times. Is the service held every day or only on Sundays? In the latter case, you forgot the day abbreviation Su.
By the way, we write the time in 24-hour notation and do not abbreviate minutes.

Welcome to OSM! You seem to be having problems finding your way to an address. If you need this for a drawing, do not enter it in the data. Check whether the address is entered correctly (at the main building, not on the way to the house). If you need help finding the correct approach, just get in touch.
