Counter staff very helpful. Any doubt on the hotel they will answer us immediately

Okay, but much better options exist if you have the money and book in advance. First of all, its a separate class of hotel situated within the very same Marriot (which is higher end), so consider this a class below the actual Marriot. The exit is separate, and leads mostly to nowhere, and you will most likely enter the real Marriot part of the building at first, but thankfully staff knows this is a common mistake and leads you through a small hallway of about 200m to the other reception where you will be greeted by just as professional staff. They don't include any toiletries but will deliver them swiftly to the room door if you need any, I guess its ecological, in their mind, but practically..ultimately pointless and saves no one's time and energy. The room itself is a bit of a step down from regular 4* chain hotels - the size, the leather on the furniture is torn and worn a bit, and it shows its age and class. There are similarly priced competitors within the same 1-2km range, who do a much better job, plus better view, for a few bucks more. It should be priced a bit lower in order to be a good deal and vibe for the money. Ultimately an okay hotel, no one will be disappointed, but the value to me just isn't there, and the real Marriot is in the same building, but you are getting the cheaper version of it, watered down.
