It is not possible to sleep in this apartment, do not stay!
We booked this apartment for three weeks, and noticed as sound coming from outside the bedroom. It sounds like ventilation/compressor pump/machine and is constant between 6am and 10-11pm on weekdays and is VERY noisy. We asked if we could change apartment or if we could cancel the booking as we worked during the day and was horribly tired which they did not let us. We hated it, and I am so happy that these three weeks are over.
The hot water did not work for the first day (was however fixed with help from city relay).
The living room windows are facing into some sort of factory hall and the bedroom windows are blocked so you can’t see outside.
If you are only booking on weekends you can as the noice is only there on weekdays.
