Low Blow
Teacher here, using hostels for most trips with students. This is simply not good enough. Pros: Great shared spaces. That really is all.
Cons: Wifi is VERY slow to the point where it is unusable for anything but text. No way to get a coffee after 10pm (No machine, only sold in bar, which closes at that time). Very small rooms with six three-story bunkbeds (Glad I am the teacher and have my own room), no windows that can be opened, and not enough ventilation to make it breathable. Only one shower and toilet for 6 people?!?? (Make some shared shower areas, if that is the room sizes you are going for) Breakfast is the most sad experience I have EVER encountered in a hostel with that service provided. Showers can just about deliver (Three showers now, none very warm). Mattresses are coated with rubber so as to make sleeping rather sweaty. But yeah, easy to clean for the staff! There is such a thing as too effective...
I know I am not at a hotel. But this is just below standard for normal hostels. Even a cool brand and logo can't save that. Do better. ESPECIALLY with the coffee, that is just a low blow, when working late. I mean, never seen a hostel without a damn machine for that service. And in many you can make it yourself in the room with a kettle. The reason for two stars and not one is the shared space, which are fine.
