In this case my father stayed there, and unfortunately his experience was not entirely satisfactory.
The communication is through a switchboard. If you have a technical problem, they take the message and pass it on to the specialist, who may or may not be available. In our case, we called on a Friday afternoon and the technicians came on Sunday morning.
The problems were with the heating (in the middle of December) and with the TV:
- The heating was not working properly. The digital thermostat was broken, you couldn't see the numbers well and you couldn't see what temperature you were setting. When we somehow managed to set the thermostat to 22 degrees, the actual temperature was 28 degrees and you couldn't stand it. My father had to disconnect the fuses to be able to sleep for two nights. And in the mornings the apartment was very cold, since the heating was off the whole night. We alerted the support team on Friday, and when they came on Sunday they left it exactly as it was: thermostat 22 degrees, actual 28 degrees.
- The TV was not showing, we also called about this issue. On the last day in the morning (in a 4 day stay) they put in a chromecast and fixed it. But the other 3 nights there was no way my father could watch TV.
It was a pity that the stay was ruined because of the temperature, because the rest was quite ok. Even without TV, the apartment is nice, well equipped, just as it looks in the pictures. A bit soft mattresses in my opinion, but fine. But heating is a must when you rent an apartment in Europe in December.
