what were you expecting?
The Piazza which is in the new City Lusail is also considered a luxury place. You couldn't get that sort of premium location in most countries for that price.
Here's some info on Lusail
Lusail City - North Doha
In the Lagoon Towers (The world's tallest leaning structure) it went from 950,000 for a 3 bedroom 170sqm apartment to 2.2m in the span of a year and a half - two years.
That's because the underground station was announced nearby, it's on the sea with a view of the Pearl, Lusial, the Lagoon, AND Westbay, has a shopping mall, etc...
I recently bought another apartment 2bedroom 145sqm on the 21st floor for 1.65m
Doha is one of the world's best real estate investments on par with Shanghai.
