We recommend you to book accommodation in central Helsinki as the wedding venue is easy to access from the center, and before and after the wedding there are more things to do there. As the wedding starts at 15:00 on Saturday, May 4^th, and lasts until late night, we recommend you to book from Friday, 3^rd, until Sunday, 5^th. Unless you have an early flight on Saturday in which case from Saturday May 4^th til Sunday 5^th is enough
