TLDR: comfortable stay reminiscent of a hotel/hostel hybrid. Enjoyed it. Here are the highlights:
1) free breakfast and coffee downstairs everyday
2) no toilet in room - only shared toilets on the floor, not a big deal
3) room is comfortable but noisy as its right next to a main street. Room has a shower and bath
4) stayed in two places in Prague - fairly priced and convenient location
5) tiny and slow elevator may be annoying if you live on a higher floor but wasn't a huge issue for us
6) most closely resembles a college dorm suite - can meet new people or can just stay in your room
Would stay again. Hope it was helpful.
