Check-in can possibly be a bit gimmicky. I was lucky/happy there was a woman who also needed to get inside at exactly the time of my first check-in. By the time I had my laptop ready (I don't have an Android or iOS phone, can hotspot through my phone) she already opened the door.
I heard a British guy had been at the front door for about an hour and a half later that night. Maybe this Vikey thing has no issues for a lot of other people, but for me it's not ideal, and I probably won't book a place again if it involves this kind of check-in. I got out the next morning, so never actually used the Vikey site.
It's also a bit weird if you arrive late and would like to use the lockers, but other people are already in bed with the lights out (I think this was around 22:00) and it's very quiet in the room. I left my bag near the window, and it can be me, but I was never really comfortable with that.
The bed (I was in) was pretty unstable and every little turn the person below you does is noticeable. Guests kept coming in in the night, and people started to get up around four or five 'o clock. That aside there is a lot of traffic in the street in front of the hostel with plenty of scooters and motorcycles, so I hardly got any sleep in in the first place. My own house is also quite noisy and also in a busy street, but during night this was a bit much.
Don't know if some of the showers are supposed to be only cold water, but by the time I noticed I just wanted to get outside again ;)
For 38 euro's a night this place was far from value for the money for me. Maybe this suits other people, didn't work for me..
