Ben Affleck and Lindsay Shookus have set up home together.

The 'Justice League' actor is renting a luxury apartment in New York's Upper West Side, which will be his base when he's in the city, and the 'Saturday Night Live' producer moved in around a month ago, sources told People magazine.

The 2,761 sq ft property boasts three bedrooms, stunning views of both the Hudson River and Central Park, round-the-clock butler service, a pool and a private movie theatre, with leases on the building averaging around $28,000 a month.

Ben recently spent Thanksgiving with his estranged wife Jennifer Garner and their children Violet, 11, Seraphina, eight, and five-year-old Samuel.

While Lindsay didn't join in with their celebrations, it was reported afterwards that the 45-year-old actor has introduced his new partner - who he has been dating for several months - to the 'Alias' actress and they enjoyed a late afternoon lunch last weekend.

The group met up at Farm Shop in Brentwood, California, where they enjoyed a bite to eat before heading back to 45-year-old Jennifer's home.

A source said recently: ''Ben and Lindsay looked so happy to finally be making their relationship legit with Jen. They've had to tiptoe around and Jen has resisted having the kids hang out with Lindsay. Ben was dressed up and seemed to really want to make a good impression on Jen - like how clean and healthy he looks. Lindsay looked a little nervous but was getting support from Ben.''

Their reported meeting comes after '13 Going On 30' actress Jennifer was said to have no problem with the pair's romance.

An insider said previously: ''Jen knew about the new relationship and still chose to go on vacation with Ben for the 4th of July. She is OK with it.''
