Check yourself in at anytime after 4pm! No need to meet up just get your key from a lockbox outside and enter the apartment. A check in link will be sent to you with pictures and instructions of how to get the key and how to locate the apartment!
It is a brand new modern apartment with a balcony located in central Old Town just a few steps away from all the cafes, bars, clubs and restaurants. It is a quiet area and it is also very safe as it has a police station just in front of it. Enjoy!
