We were a group of three friends, and this apartment was the perfect base for a long weekend in Copenhagen. The communication with City Square was very easy, and self-checkin great, with the option of early or late checkin/out. The apartment was very clean with extremely comfortable beds and lots of light, and a nice kitchenette with good appliances. It is located right in the heart of the city, easy walking/biking distance or metro from anywhere in the city, and near many nice stores and restaurants. The building was quiet and secure, the only thing to mention would be that the street and neighbours putting out bins daily before 8:00 was pretty loud, so if you are a light sleeper and/or want late nights out, be aware! For us it was fine as we are early risers.
