We really enjoyed our short stay at Karl and Arlene's apartment. The place is very beautiful and we loved the 50s design of it. The view is stunning and there were a lot of details that made us feel very welcome.
Check-In and check-out were super easy and we have nothing we could complain about.
Also, the neighbourhood is really nice and if you're not that lazy you can even take a relaxed walk into the city centre from the apartment in about 40mins (if it doesn't rain)... We'd definitely recommend this place and stay there again.
