oh hey Sundragon, Yes I agree sticking a mesh network in an apartment that's crowded is just a bad ideal since these days people think that Mesh is the IN THING and don't have much of an understanding of Wifi Networks.
As a suggestion and pretty much the best thing you can do in a New City Apartment is get a either a used Ruckus AP such as Ruckus R610/R710.. R610 has over 500+ different antenna patterns to get your data to your device or the R710 has over 3000+ different antenna patterns. Both are 802.11ac Wave 2 APs. Note it supports DFS channels and has an intelligent channelFly system. Ruckus is enterprise Wifi Gear. Load Ruckus Unleashed firmware and you are set. No support contracts needed for using Unleashed firmware.
Here's a video the further understand about Ruckus Adaptive antenna which will help you more than any consumer Wifi Router/AP.
Ruckus is one of the best Enterprise Wifi gear that handles wifi inference and high density situations.
I've been deploying Ruckus APs since 2014 and only recently started recommending friends and family and people online in getting used Ruckus APs. Used Ruckus R610 are on average $150 on ebay and can get them as low as $99 each towards the end of the year when large companies upgrade to Wifi 6. R710 on average are about $200.
Anyway if you have any questions let me know..
And don't even both with Unifi APs since they are just prosumer APs with standard Antenna designs and their firmware is horrible if you don't mind the up and down development.
