We stayed at Frederik.
Pros : the location wasn't near the tourist area however, 2 mins walk you can reach Metro station and go there (3 stops) and at the end of the line is the airport. So it's very convinient for us. The house itself was so nice , clean and lots of needed amenities. Nice host. Love this place so much ❤
Cons : stairs only. Make sure that you asked your unit level.
