Stayed for a week in a hostel-style room. Overall a pleasant experience and would recommend to light travelers. The check-in line was considerable and quite often very long each time I came back to the hotel for the day.
Inside the room, there is a tiny table with 3 seats in one of the corners. The bed has 2 AC outlets, a light, and a tiny counter just wide enough for your phone/keys. Your locker has towels in it and is big enough for a backpack or a small suitcase, but definitely not a larger one. Bring a lock. The thermostat is controllable - the other guests made it rather cold most of the time (which is a good thing!)
There are 2 bathrooms for the room, each equipped with a shower and a toilet, along with 2 sinks in the common area. The front desk provided me with body wash and shampoo when I asked, but didn't have combs.
Even though our hostel room housed 8, I don't believe more than 4 or 5 people were staying in the room at the same time. The guests that I roomed with were mostly quiet and clean. The room is cleaned/the small trash can emptied each day, and there is a hook on the side of the bed to hang sheets/towels to replace.
The bar adjacent in the ground floor was never open. The restaurant on the roof didn't seem too appealing to me, although apparently they do have room service if you're feeling lazy.
Also, possibly mildly concerning - the wifi is completely public and doesn't need any password or login redirect to access.
Overall, extremely affordable, very central location close to bus lines and metro, and most places at this price point won't have central AC. If you don't mind the hostel-style living this is a great option.
