If you are going to fly from Vnukovo then look for apartment close to subway station "Ugozapadnaya" .
If you are based in UUEE then Himki is not a bad area.
I've no idea for Domodedovo.
Bear in mind ,traffic is horrible in Moscow,so the closer to the airport the better(unless you fly once a month and it is all the same to you)
