We booked one of Elwin's apartment (734) over the weekend for 3 nights.
What we liked:
- Apartment was nice, clean and spacious
- The kitchen was well equipped apart from the frying pan/wok.
- Elvin answered very quickly all questions
- Many trams stop close by.
- AH supermarket is close by
Room to improve:
- TV seemed very small
- no shower curtain, but I think this is standard in Holland
- frying pan/wok was not usable (rusty)
- we had to restart the WiFi server to be able to access the internet

Unfortunately our booking was changed from room 734 to room 732, which meant we had a massive crane right in front of our window. This, I suppose, was the reason somebody moved possibly from 732 in our originally booked room. However Elvin assured a free night with the next booking should we return. Views of 734 would be nicer as well as it faces Scheveningen.
Even though there was a hick-up I would still recommend to book the apartments with Elvin and we seriously consider coming back.
