Have put up my apartment for rent on Housing and all the other major realty sites.
In my experience, Housing has:
a) The best UI and UX
b) The best customer service in terms of tele-service, the agent coming over and taking photos, etc.
c) The best response - on the other sites, even when I clicked and uploaded my apartment photos, the response rate on Housing was the best.
d) Interesting add-on features such as 'lease agreement' maker and so on (which I only used to draft my own agreement with my tenant)
As regards 'aggressive campaigning', so many other companies are burning more expensive television moolah (e.g. Car Trade, Car Dekho, YepMe, Practo and more). And yet, this company interestingly attracts more than its fair share of criticism of aggressive campaigning - possibly thanks to some of media houses that also run property portals :)
Didn't go down that way for me. Their sign up form kept giving 503, and each time it did that, the form reset saving nothing I entered. That is a UX fail.
The form is not clear on expectations, when you don't follow them, it fails, resetting itself. That is a UX fail.
The service is only available in Metros, but they never say that during onboarding. Even their sign up form has all Indian cities. You put up your listing and if Housing is not in your city, you simply never get contacted. Fail without notice. That is a UX fail.
I managed to have 3 accounts with same e-mail. That is a massive, massive incompetent engineering. That is a UX fail.
UX and UI are not the same thing. Beauty is seen. Experience is felt. Housing's interaction design is absolute junk.
I'm also fond of their branding somehow, and their aggressive campaigning, their staying away from TV, and them not forcing me to download their apps.
But that all falls short when the website fails 11 times just while I'm trying to put up a listing.
