Paul is a brilliant host as is his wife. The apartment was superb - everything I wanted for this stay. I was made very welcome from the start and was made to feel part of the "family". Paul invited me out for a few beers with his mates which I appreciated a lot.
The location is spot on too - really easy to get around with the MRT just next door and plenty of busses just outside the lobby entrance. You can't go wrong for food either - every type imaginable is on tap downstairs and across the road.
My room was excellent, the aircon developed a slight fault but Paul had it seen to immediately, the bed was perfect and there was even a top notch TV in the room. I had great internet connection (barring one day when the provider had problems - hardly Paul's fault) and free access to the kitchen facilities.
Overall this was one of my favourite airbnb stays. If you're in Singapore for a few days I can't recommend Paul's flat highly enough.
