    We ordered a private room in the hostel, to have the "hostel experience". However it turns out the private room is on another building 3 blocks away (still same distance from city center), which disappointed us a little. On the other hand, we could go back to the main building to use the hostel installations (e.g. billiard table) any time we wanted, and we had a private bathroom which we didn't expect. All in all the experience was great and this is very recommended!

    I love Hostel Mostel and would never stay anywhere else in Sofia. The atmosphere is so welcoming and fun, the common space is comfortable, and the facilities are generally clean.

    A biggest hostel in Bulgaria offers rooms in two separated buildings. It's a very cool and positive place. Strongly recommend.

    Another guy snore very badly so I can't have a sleep. I think its time to ask such questions before. If they snore they need to book single room

    The staff were nice. Met the most travellers here. But the breakfast was not included like it had been stated. And the crowd of long term older residents made the atmosphere a little off

    Stayed in private room which is in separate building away from the hostel which I like. Clean, spacious and slept well. Good atmosphete in hostel, nice to chill or have some drinks and meet people. However as mentioned before seems to be some long term residents who were in the hostel the whole time. Although all they seemed nice enough, can be off putting having group of drunk older men there I’d imagen more so for younger females.

    This hostel is okay. A note for female travellers, there seemed to be A LOT of very old men loitering inside the hostel reception which even made me, a male, uncomfortable. A lot of the men would try to approach the female travellers and also just behaved very strangely. The hostel itself was basic but fine, the toilet/showers were not well maintained but still usable and okay. The bed was basic but clean and maintained so not a problem.

    Good experience here before but disappointed this time. Annex dorms were cramped and dirty. No soap in bathrooms. Main door not locking properly. Not all beds have plugs. Main common room looks tired and could do with refurbishment. Very affordable price if you're looking for somewhere to crash, but that's about it. It would also be helpful to specific if the dorm is in the main building or an annex down the road.
