Having this been my second time staying at the Studio in two years, I can say that the apartment is still a favourite and a great listing on Airbnb. With this particular booking there were issues with the check-in and the cleaning (it simply wasn't done by the check-in time of 3pm), and although quickly rectified within half an hour, the cleaning was not done to the standard I would have expected from a place that is consistently booked up with guests one after the other.
The airbnbutler key service were very good at sorting out any problems I had due to the host being away from the city during the dates of my booking. Location is great and the apartment is very modern and perfect for a quick getaway in Amsterdam. I would just recommend a deep clean because the place is starting to show signs of wear and tear.
