Roelant was a really easygoing host who left us to our own devices mostly. We stayed with him mid-week so he was working and we were out a lot, but we got on well and shared a beer.
Just to note: the bedroom is two floors above the rest of the flat which offers a lot of privacy but may not be for everyone.
You have a key to the apartment and are free to use it at any time which is great, it was a really good set up :)
