Hi again. With your budget in mind, here are a couple of suggestions:
Prices are from Asia Rooms but you should be able to get similar rates if you speak to the hotel direct I would have thought (might need to be lucky with the Mandarin!).
Marina Mandarin, SGD 215.80
This would be my first choice at your budget if you can get it at the rate above. It’s one of the better hotels in Singapore and right by the Esplanade & Marina so a good location. Pool looks decent.
Parkroyal, Beach Road, SGD 170.00
This isn’t by the Marina, but still worth a look. The pool is nice and quiet and the hotel’s pleasant. I was here for a month when I first moved here. Location is still pretty central and it’s right by the Arab quarter for some great food in the evening.
Peninsula Excelsior, SGD 217.75
This is in a decent location too, right by City Hall though I don’t know the much about the hotel. The pool looks ok from the photos.
If you want any more info on Singapore feel free to drop me a mail.
Cheers
Ben
