I live nearby & visit glass alley fairly regularly... daytime is my preference, the girls seem more relaxed than during the evening, & it’s totally safe with no hassle. €50 for 20 mins is standard, oral & as many positions as you want to fit into your 20 mins. Day shifts seem to be 10am - 6pm, most girls are east-European but all have enough English to get by. Just saw a lovely South African lady called Bridget this week, if you bump into her well worth a visit. She works Fri, Sat, Mon daytimes. Enjoy your visit!
