I would recommend a stay at Cityden appartments.
Very spacious appartment. We stayed with 5 people and had an appartment with 2 bathrooms. The sofa bed had the quality of a full size double bed (which is not always the case in other hotels). Bus stop nearby to go to the center.
One minor comment is that the fire alarm went off while we were sleeping, with a comment afterwards we should not worry.
Thanks for having us!
