Hotel is nice but rooms are oriented to design, not to efficiency or comfort.
It is supposed to be a Marriott Bonvoy reference but it is not at the level.
Main problem comes from the lack of honesty of manager. Don't give your CC details as they try to charge you undue services. And when you leave the room, request to make a formal check with hotel team in order they don't charge you more than expected.
And request a final invoice.
My advice will be to avoid this hotel at any case. Sad attitude met in opposition to all other hotel that we got in 11 days in Iceland.

Beware! Thin walls/windows!!. The lobby and restaurant are quiet, but the party on the street was booming in our room on the 3rd floor in the room farthest away from the music on the street. The music was 96dbs at 10pm and they turned up the volume every hour. I’ve never had such a horrible experience st a Marriott hotel - the least the owner could do is provide ear plugs!! We bought our own but honestly, the plugs didn’t help. The base made the bed vibrate and it was impossible to sleep until 1sm when the music fonally stopped. I would have given the hotel zero stars, but it is clean. They location and building has many trip hazards, so people should prepare for that. I fell flat on my face on their doorstep. I do not recommend this hotel and I will never return.

Great location and nice room BUT way too loud. First we are Marriott titanium members which didn’t seem to matter in this hotel. We were given the room on street side right near the bar. We had an early 14 hour flight the next morning so we needed some rest. Vibration from music and partying kept us awake until 3:00AM. While understandably there is no AC in room it is possible to open the windows but with the noise level on high volume that was not an option. This made for even a more uncomfortable stay. Unless you plan on partying until the weee hours of the morning we do not recommend this hotel.
