I stayed this week at Marriott Athens and Moxy and few months ago at Fresh Hotel and New Hotel (and Marriott too)
I would choose always the Marriott (new / hard product / roof top bar & pool / lounge / free parking / very comfy / etc) but it’s located at Piraeus and I need more often to stay near Athens center
Moxy to be honest is nothing special but very new … no parking and the nearest one at 300 mt (not the best by walk with the luggage). Typical fast food restaurant as Moxy’s. From the 2nd floor you can hear noise from the street in the night.
The Fresh and the New hotels are located not in the best area of Athens …very bad buildings in their areas …
I would choose always the New Hotel (roof terrace / much better restaurant/ private garage Underground) but often the rates are 60-70% more than at The Fresh
the fresh is not bad, recent property, garage (ext) just in front of the hotel
