We booked the apartment as a family of three (two adults and a toddler). First of all I would like to mention that the communication with the landlady worked well, the apartment is really beautiful, modern and very clean! BUT, we have never experienced such an ice-cold apartment, where no heating works and, especially in the toilet and bathroom, the temperature was almost like outside (our trip was in late November)!
We immediately reported this to Daphné, a plumber came and tinkered around so that the heaters were at least lukewarm, but nothing more. The only thing that kept us reasonably warm in the living area was the mobile heater but it was always cold in the bedroom and icy in the toilet/bathroom, without exaggerating. That's such a pity, because it ruined our stay in this apartment.
conclusion: it’s a very cozy apartment but we cannot recommend it, especially with a small child, in the cold season, as long as the problem with the cold is not solved.
