We were two people staying at Karl's for 3 nights.
We liked the privacy, own bathroom, own access to the studio and easy parking on the street right in front of the place.
The studio is located in a quiet area, there's no noise at night, however it takes about 40mins to the city center and to the beach by car. We liked the nice bed sheets, thick curtains and wifi was fast and reliable.
The studio is however tiny, bathroom as well, 50x50cm fridge is on the floor, kitchen appliances are crammed together and takes some planning to prep food on miniature counter.
Mattress on bed was too soft and we could feel springs thru the thin outer layer.
The owner is very friendly and helpful and the price fair. We can recommend for a short stay.
