If anyone familiar with the area knows who best to contact with regard to renting (6 months plus) one of those apartments/town houses above Greenbelt, it would be much appreciated. Either there or contact details for any other good apartments within a couple of minutes walk of Ascott and Shangri La. Thanks in advance.

suggest you research www.ayosdito.com they have acommodation section, narrow it down to Makati and see what you get

You can find along ayala avenue crossing green belt. I stayed in BSA tower makati but the downside is the convenient store it situated couple of blocks away. In ayala avenue you can find almost anything there.
