The privacy in the bathrooms is NON EXISTENT. The 3 showers / 3 toilets are dorm style cubicles - 2 showers, 2 toilets and a combined shower-toilet cubicle.
If you are coming in a mixed gender formula (we were 11 girls and it was somehow manageable, but still - not cool), it might be a challenge.
You also absolutely need flip flops for the showers and because the the stairs between the kitchen and the bathroom area are very slippery. (one of us slipped when getting out of the shower and fell pretty bad.
The very tall bed is questionably accommodating for 2 - it is super high and for people that are not used to that can be scary, as the safety bars don't seem too reliable. Also, both ladders - from the tall bed and the bunk bed - are not fixed - you need someone at all times to get out of the beds.
The windows from the street rooms do not close well, which makes the rooms very noisy.
The normal beds are super comfortable, the location of the apartment is super good and the apartment looks pretty nice and cozy.
