Great base to discover Copenhagen. Easy to reach the city center by bus (15-20 min) or by bike (10-15 min). As mentioned in the description and other reviews you can hear the kids in the morning, so if you come to CPH to go out late and sleep in in the mornings, this might not be the place for you. But for us with two small kids and getting up early it was the perfect place.
One of the bikes had a flat tire when we where there, but we where mostly using public transport anyway. But if you plan to use the bikes we recommend to get in touch with Joy before your arrival to check, if the bikes are ready to go.
