That wasn't even a close call this episode; the apartment they "chose" was clearly the best of the three.
My only problem with this ep (indeed, with HHI in general) is that the producers have got to do a better job with the scripts/fake storylines. If you're going to have a couple griping about the prices and/or noise in their new city, maybe don't use the couple that's moving from an expensive/noisy city in the first place. No one moving from Washington DC is going to be shocked(!) by housing prices in another international city.
And for the love of everything, Show, enough with the trailing spouse giving the "I gave up so much to come here, so I should get what I want" line. It's annoying. Maybe a better line for the script would be, " I'm hoping to get work myself, and being closer to the city will put me closer to work opportunities", or " I don't speak a word of (fill in the blank with the native language of the country), and being in the city puts me around more people who speak English", or even, " I prefer city ( or suburban) living." Any of those beats the whiny. "I gave up so much to come here!" foolishness.
