tl;dr: Excellent. Will stay again.
Room sizes are good. They are bigger than they look in the photos.
Very well equipped kitchen.
Feels like home.
Secure parking.
WiFi is okay.
Flexible check-in / check-out time as long as it is after 3pm / before 10am.
Good communication from Raymond.
Raymond also left a lot of useful information in a folder, including maps for bus and tram stops and timeables, supermarkets, take away menu etc...
The only cons is weak shower.
