You get what you pay for. The place is an excellent value for money, but far from the centre, with no restaurants or shops around (specially at night).
The place itself is a bit old and worn out, really basic. Also quite noisy, since the front door is actually a glass door, you can hear everything from the outside. Anyway, none of it matters matter if you just need a place to sleep, like I did.
WiFi works well and I appreciated direct connection with Florenc bus station. I also appreciated washing machine and the balcony.
The owner is helpful and communicative and replies to messages straight away.
