Is there any Mass we could attend or anything else interesting on xmas eve in Istanbul?

"Saint Antoine" has Christmas mass and I am suer there are more.
Istanbul for sure has a lot of interesting venues with or without chritsmas as a reason......There are some restaurants with parties and international hotels as well participetes to this holly & festive period.
Happy travelling,

What about NYEve? we'll be there from Christmas Day until the day after New Years day and would like to find a suitable spot to see in the New year. Any suggestions? Thank.s

Main point for street celebrations are in Taksim square. There are a lot of parties going on at bars, restaurants and hotels. Walking down to Istiklal from Taksim will be a challange that night. Best to book a restaurant and have some fun with locals.

Happy travelling,

change of plans. Dec. 24 is our first night in Istanbul so we would like to go to the Blue Mosque and maybe one other sight. Maybe a Turkish Bath?

For Xmas midnight Mass, there are some churches in Istiklal Caddesi where you could go.

For a Turkish bath, go to Cemberlitas, a 10 min walk from the square beween Aya Sophia and Blue Mosq, in the direction of the Grand Bazaar.
