I have not stayed in the apartment-hotels often, so I was a bit concerned about how it is all going to work (e.g. check in). But it went well, I got entrance code on my phone at 4pm as promised. In general I do not have any really negative things to say. Clean, simple, means-business accommodation. It is a bit "strange" that there are no personnel whatsoever but I guess it is OK as long as everything works OK (and there is 24h phone number in case of emergency, fortunately I did not have to use it). The room had kitchenette (small induction stove, coffee maker, refrigerator) which was good to make your own snacks as well as tea/coffee (plates, forks, knives are also there).
Couple things which are a bit annoying rather than negative:
1. It is not possible to lock the room from inside (well, maybe it is just my problem).
2. There was no other choice (at least I did not see it) for bed, only 2 single beds available. As a couple I would definitely prefer double bed. Again, maybe it is just me...
The location is near the large shopping center with the road just outside the building (it is approximately 10 km from the Oulu airport and the same distance from the Oulu center). But surprisingly it was not too noisy.
Like I said, all-in-all - not bad. Maybe not the most romantic hotel but then again it all depends on what are your plans for the visit.
