You better to have a site visit and take a look. For older condo at MK, particularly those near to One MK and 163, many units were rented out to those supermarkets and restaurants as hostels for their foreign workers. Come around the time these workers go to work or the time they finish work. I am not discriminating these foreign labor. They have the rights to stay if their employers pay the rents. But, sometimes, their behaviours are annoying. Vista Kiara from what I hear and I observed seems to have a lot of foreign labor.

Tell your relative to stop, this practice downgrades the value of his/her condo. Thank you.
