The managers of this place are super profesional, the place is spotless and there are lots of welcoming things: toothbrush, shampoo, coffee, etc.
All interactions are done through their website though, and systems sometimes have issues.
In my case, I have a double-barreled surname which wasn't registered properly, this implied that I couldn't check-in following the normal path of the system, I had to contact support.
Also, after you check-in, is not intuitive that you have to follow a wizard to see the second code that you need to open the apartment's door. At first I thought I was a boomer but the next day I saw a young couple having the same issues I had to enter the flat (not knowing there was a 2nd code).
None of these difficulties can happen to you, now that you know them, and the flat is really well taken care of: super clean, exactly like the photos, etc.
That's why I am giving it 5 stars irrespective of the tech issues.
