room was towards the street and had 25 degrees when we arrived. Without activated heating. Turning it of did not improve anything. This answer is just an insult.
You can open the windows, but then it is like sleeping in the middle of the road. And as soon as you close them, the room heats up pretty quickly, cause of the warm walls.
Even with closed windows you can hear the very loud street at night whilst trying to sleep. The emphasis is on trying.
Leider heizt die Lüftung ab Oktober nur noch. Das Zimmer hatte gemäß Thermostat 25 Grad, die Antwort "Fenster öffnen". Zu einer Hauptstraße raus. Mit Baustelle.
Zimmerwechsel ist nicht möglich, da das Hotel ausgebucht ist. Es gehen 3 Zimmer zur Hauptstraße raus, wer die hat, hat halt echt gelitten...
Badezimmer groß, leider die Dusche komplett verschlimmelt. Ebenfalls Schimmel im Zimmer selbst.
