Our stay with Demmy was really good. Essential for us was the free parking right in front of the house. The kitchen and bathroom are clean and cosy. The location right at the Thames is very nice.
The communication with Demmy was always possible in a reasonable period of time and all questions were answered. Sometimes the communication could have been a bit warmer and more welcoming, but we had lots of privacy. The WiFi signal in my room was very weak and therefore not reliable for eg video calls. Thats why I deduct one star. But I can absolutely recommend Demmys place to others.
