Comfortable sitting area with smart TV was great for relaxation days. Fully equipped kitchen with kettle, coffee maker, microwave, etc...Really convenient, free parking. Easy communication via whatsapp for questions, etc...
It took several hours for the apartment to heat up so maybe turning on the radiators prior to check in would be a nice touch. Also, providing a small amount of coffee, tea, staples like sugar/oil/salt/pepper would be great. There was white dog hair on the couch and we found clothing and some trash left behind by previous guests in the furniture. Add some small toiletries and a hair blowdryer as most people don't travel with these items.
