This is not a hotel but an apartment. Even given that, there is several points to be improved.
To get access your room, you have to obtain two key-codes in advance. However, you are not provided with this important information unless you make a contact to the property owner autonomously. If you go there without obtaining the key-codes, you will be locked out on the cold street!
Fortunately I could get my codes just a day before I leave my home. But there was a girl who came to this property to stay without codes and she was hopelessly alone at the gate of the property in a late winter evening until I came back there after my business. She made several phone calls to operating companies but no body responded.
The room is equipped with a nicely-looking kitchen. But there is no salt, sugar, oil, etc. So you have to buy or bring everything if you want cook there. Of course you can buy them at near supermarkets, but you will waste much unless your stay is long enough.
The nicely-looking electrical ovens have a quite confusing unintuitive interface. However, no operation manual is provided. It took 15 minutes for me to figure out how to use it.
There is a built-in laundry machine, but there is no detergent, of course.
You can find no towels and no tissues, of course, although another apartment in Madrid where my colleague stayed provided them.
The water drain in the shower booth (no bath tab) is very clogged. So you can easily flood the booth.
