* London / Marriott Maida Vale / OPEN (may be closed on holidays); Lounge currently under renovation (to be completed in July 2016);temp lounge currently located on mezzanine level above restaurant; 07/18/16 update
As of today, the lounge is still in the temp location. In fact, there seems to be a LOT of renovation work being done at the hotel. Best I can tell, floors 3 and 4 are closed (stairwell has signs on the doors declaring them hard hat areas).
Breakfast is served every day in the restaurant, nothing in the lounge. They do check room numbers.
Lounge is open every day, 0600-2400, but no evening food or drinks on Friday or Saturday. You can, however, get complimentary beer and wine (house versions) in the bar if you mention being eligible for the lounge. In fact, on Saturday when we asked for two glasses of wine to take back to the room the bartender gave us two glasses and a whole bottle of wine
Lounge also says it is open for afternoon tea every day. This seems to mean they put out chocolate brownies, as coffee, tea, water, sodas, fruit drinks are always available.
There is a terminal there and it tends to be quiet and not very crowded, all of which are nice features.
Unfortunately, the beers are Foster's, Beck's and Stella. Yellow, fizzy beers, one and all
No key needed to access. Just walk into the restaurant and up the stairs. We were even able to get up there Sunday night, when the restaurant was closed.
