A few years back, I made a spreadsheet of the average customer rating for each (or most, I couldn't get details on a few) Four Points location (in the US at least) from the Marriott website/app after reading a comment about Four Points quality and customer perception of the brand. There were some definite bright spots, but many had mediocre to even terrible ratings.

• To be fair: 27 out of 102 properties had a rating of 4.0 or higher (Three of those were 4.5 or higher). I consider 4.0 and over to be good.
• 50 out of 102 in the 3.5 to 3.9 range. This range (in my experience) can be mediocre but it varies. The property could simply be dated but functional, which is fine. Perhaps people think the rooms are small, but if the hotel is in midtown Manhattan what do you expect from a Fairfield? Or there could be problems with the property. In the 3.5 to 3.9 range, I peruse the specific reviews to get a feel for the property and determine whether to stay there or not. (e.g. if there are lot of complaints about the pool being closed for renovation, that's fine for me, I don't use the pool. It may matter to you though if your kids are looking forward to using the pool)
• 20 out of 102 in the 3.0 to 3.4 range. Reviews are generally bad to get an average in this range. I would hesitate to stay here.
• 5 out of 102 were: 2.9, 2.8, 2.8, 2.5, 2.2. (Four of these have closed, or are no longer Marriott properties. The other one has improved from 2.9 to 3.2)
