Stayed at Avra By Smile Hotels for one night prior to flight out of Athens Airport. Nice and clean hotel and has restaurant that was open till 1030pm. Restaurant food and service was great, we got down there couple mins after 10pm without any issues; also got 15% discount card at check in.
We used their hotel van for transport. For reference they have pick up from Airport on the 30s and leave hotel for drop off on the hour. We landed at 830pm got bags and were in bus lot by about 850pm and had to wait till 930pm for pick up. They have link to track van and see image of what van to look for, very helpful. They ask you to notify if need transport to Airport, so told them at check in we needed 6am for van to airport next morning, they just asked us to be down 10 mins early.
They will not wait longer than time needed to load people/luggage, so if your tight to the 30 min mark to catch van know you might end up having to wait for next one. They did meet the timeframes they state. Was nice included perk.
