The place is beautifully decorated and perfectly located, there is nothing to say on that.
However, I feel the place is overpriced compared to the poor level of service provided. It came as a shock that I had to pay 20EUR extra for a blanket in the winter, whereas the one initially provided was so thin that it would rather fit spring/summer temperatures, and whereas the heater was so weak.
Obviously this is one of those places that are managed by commercial peeps and only meant to be rented out to short term guests, but I would still advise the agency to properly take into account what makes a place livable for their guests.
