The heating arrangement in the flat was very inconvenient for us as we couldn't control the heating ourselves; all temperature adjustments had to go through the host.
Even though Michael And Martine complained since day one that they were getting overheating alarms in their remote control app, the wall thermostats showed 10 degrees in the flat. Michael And Martine had told me that because they control the system remotely, the thermostats won't show the correct temperature. Still, my family and I felt uncomfortable and cold (it really felt like 10 degrees). I asked them many times to turn the heating on, and they were texting me that the flat had reached 23 degrees (which was their limit) and that the radiators would turn on only if the temperature dropped. They also accused us of having interfered with their system.
On the last day, the host complained that because we had interfered with the system, they had to come to fix it. I had to actually step out of a meeting at my new job to let them know that they can enter as we weren't there at that time.
On top of the whole heating situation, the bank bed was super squeaky and I was waking up all night. The shower water pressure was also intermittent.
We felt disrespected and that the host had nothing else to do than check how much heating we used and how hot we wanted the flat to be.
I wouldn't recommend it unless it's summer.
