We had a wonderful stay in Karl&Lisa's appartement. You can tell from the first moment that it's all renovated from ground up, it's impeccably clean, and has well thought out details.
I have to say I loved the tech features of the house, from the smart lock which allowed us to check in flawlessly at unusual times to the smart thermostat so efficient and easy to use. The appartment is an residential area, 3 minutes walk from the metro and near to supermarkets and other comodities. It's very quiet and lighty.
We hope to come back one day, in the meanwhile we'll suggest your BnB to our friends!
