Our stay was an adventure. We were coming in on a Sunday so the info about checkin only arrived on Saturday. It said check in is only Mon-Fri 12-17h and to call one of two numbers to give them the exact time you are coming. No one answered either of those, but in the end we were welcomed by the lovely Tariq at the reception. So yeah, they are still there on the weekend, but definitely not there in times other than between 12 and 17h, which to me is a bit strange for a hotel. They do have an emerency number to call, but don't expect to reach that from the first try.
The room we got is not in the pictures, it's smaller and the bathroom is much older than pictured. It was decent and clean, but this is an old building and with it come all of the issues of the old building charm.
The room needed 2 days and significant improvement in weather to get heated, I can imagine it's very cold in the winter. The internet signal is not the best and on our 3rd day we were greated by a burst water pipe in the basement, which resulted in us not having normal access to water in the bathroom for 2 days.
The staff did try to help out, although we also needed to push from our end a couple of times, but we came to an agreement in the end and they offered us a compensation. I wouldn't say this is their fault, these things happen and they dealt with it most likely as good as they were able to. Once again, kudos to Tariq who seems to be the person holding everything together there and the only one replying to the messager on air bnb.
