I do not expect any kind of luxury from a 2-star hotel, and I've definitely seen worse. But I've seen better, too, including in the same price range in Vitoria. Hotel Dato has a narrow steep staircase and no elevator, something you need to keep in mind, in case you travel with suitcases. You will get a good workout dragging them upstairs, 3 flights up just to get to the reception, and then a few more, depending on which floor your room is.
The first room I got had a strong smell of tobacco, in spite of the hotel no-smoking policy. When I asked for a different room, the person at the reception found another one for me, which I appreciated. However, as I moved in, I discovered that the shower head was broken and the only electric outlet was located behind the bed, in a narrow space sunken into the wall. This made plugging in a phone charger and my laptop very challenging, and taking a shower was rather inconvenient. I was too tired to ask to change the rooms again, and decided to put up with it for the 2 days I was staying.
The hotel was at least half empty, with lots of vacant rooms available. But when I asked to be allowed to check out 1 hour after the scheduled time, the answer was "no", because the room absolutely had to be cleaned immediately at the checkout time. OK, it's the hotel rules, and they don't owe any favors to their guests, right? Even the guests are willing to overlook and put up with some of the hotel's problems.
Be aware that you are being watched through CCTV at all times. I suppose it is good for your security, but I was a little surprised when I took a clean towel from the maid's basket in the hallway and was immediately visited by a person from the reception, to tell me that I should call them if I need anything. Fair enough, but I thought I was doing them a favor by not bothering them when I could avoid it. I guess not. I just hope that all the rooms are under constant surveillance as well.
The location is perfect. The internet connection was strong and stable.
