Hi We are flying from Dumuguete to Manila then overnighting & need to be at airport 530 am for international flight. Am a little worried about traffic in morning so would like to stay close to terminal 1. Any suggestions for a clean, quiet place reasonably priced 1000-1500 range, thanks so much

If you need to be at airport at 5.30am, any place in Pasay, Ermita, Malate should be able to meet your needs.
Is Bill's Townhouse in Pasay still open?
Leave at 4.30am and you should get to NAIA with plenty of time to spare....

i doubt you would need to worry about traffic at 4am ,you should make clear what time the flight is at and not what time you think should be there

Sogo branch at Harrison/Pasay
You can check in for 6 or 12 hours and easily get a taxi to the airport
Hail a metered taxi outside,don't accept an offer from the room boy to get you transport or you will find yourself paying 5 times the going rate

"Is Bill's Townhouse in Pasay still open?"
Stayed there last year, so yes hopefully still open..

The Townhouse is not in Pasay. It's in Paranaque. But still only about 140 on the taxi meter from NAIA.
I tried calling them in October, but none of the phone numbers on their website, and which I had stored in my phone and which previously worked, worked any longer.

All online booking sites indicate the Townhouse is still open. Maybe they recognised your CP number.
You seem to think that you know philippines better than me, so how is that I been in so many places that you have never even been..
