Mesh itself is fine if you have enough of an unpopulated airspace so that the backhaul isn't competing with a whole apartment complexes wireless interference. I will say though that all of the one's I've tried have had absolute garbage software and die after a year or two. I've had Asus XD5's, Netgear Orbis, and a TP-Link setup. I just bought 3 Eero's just because I haven't had a chance for them to die on me yet. The Asus was my previous mesh set up and it worked fine until it just stopped handing out DHCP on wireless. Factory resets and firmware downgrades didn't change anything. If I had the time, I would go on ebay and get some more enterprise grade gear. Cisco WLCs and Aironet APs have lasted forever when I install them at work. Just a bit more complex to wire and setup at home.
I had Netgear (with an external firewall and generic access points) before they acquired Orbi, then tried Orbi which did not have enough info/options. Then went to at least 4 different types of AX Asus units for the longest time (10+ years with plenty of options and info but started to become unstable), then recently switched to Gryphon AX due to the need for parental controls for kids. I am thinking of going to Unifi next in a year or 2, as I miss the options/info that Asus provided, and get more with Unifi.
Yeah I like the ASUS approach as well. Mine just works, and it is so easy to add another node anytime I want since their stuff is all interoperable with the AiMesh setup.
Eero (Amazon), tp link Deco, and Asus ZenWifi are all well-reviewed and perform well. If you've got to go mesh, look for a tri-band system with a dedicated backhaul channel (Eero, Deco, and ZenWifi all have models). Eero and Deco are a little more "plug and play". ZenWifi is also easy to set up, and some models give a few more config options/control than Eero or deco. The tricky part is that you don't know how well mesh will perform until you set it up in your place. Two nodes might be enough, but you might need three (or four). A 6 ghz backhaul channel might work, but, if the walls and floors in your place cause a lot of interference, you might see better perf with a 5 ghz backhaul. So buy from a place you can return it, maybe start with three nodes, test how coverage and speeds look, go from there. All three have 2.5 Gbps ports. 3 gig is a *lot* of bandwidth for a residential setup. Unless you're regularly downloading gigantic files (video, game updates), you probably won't exceed ~300-500 Mbps, and WiFi will de facto limit the perf on any device to ~200-600 Mbps. For most homes, 200 Mbps is plenty. If the 3 gig price isn't much different than ~300 Mbps (if you're in the US, it's hard to find service under ~300 Mbps), go for it, but if you're paying a premium for 3 gig, you can save some coin and you almost certainly won't notice a difference in performance. If you're in Europe, you rule!, fiber away because you're prob only paying like €40 for 3 gig.
bro mesh wifi system le better rahega na. tplink deco or asus zenwifi dono budget options hai around 3-5k range mein. extender vs mesh setup always mesh > extender 
For a villa that size the easiest fix is to ditch the idea of separate access points with different names and go for a proper mesh WiFi system, since it gives you one network name across the whole house and your devices switch between units smoothly without you noticing; you just connect the main mesh unit to your Etisalat router and place one or two more units around the villa, usually one downstairs in a central area and one upstairs, and systems like TP Link Deco, Google Nest WiFi, or Asus ZenWiFi work well in UAE homes even with thicker walls, so you’ll get stable coverage in all rooms without rewiring or dealing with multiple SSIDs.
