I know the Phoenix quite well. It's top end Orchard with SMRT next to it.
I have used it as price was good ( SGD 120-140 range ). Years back I liked it as it had PC in the room with internet ( charged for ) but over the years that is less of a novelty!

Unless anything drastic has changed there is no pool, no gardens, just a bar in the corner of the lobby, it's connected to a small mall. Rooms fairly small, it's ok, basic, the basement place for breakfast I was not keen on.
I stopped staying as I ventured to other places like the Royal peacock ( small boutique ) and places like Berjaya Duxton.
Recent favorites have been Allson near Bugis and Crowne Prince ( I think name changed now ) on Orchard which became our favorite if going with family.
Royal Plaza on Scotts has been re-done, used to be good value but the price is up I would guess now.

Changi Village, well, unless you are into the WWII history of Singapore I don't know of any reason though I am no expert there, have stayed at le meridien Changi a few times for an overnighter but not much there at all.

Have yo looked at the Berjaya Duxton, that might appeal. What about Inn at Temple Street or 1929 if you want smaller places.

Thinking about all these I wonder why I ever stayed at the Phoenix ! ( I Know, it was the 'rate' which was always a good last minute deal ).

I eat with my hands on a regular basis ( where's that sandwich gone ? ).

A lot will come down to whether a s/pool is important or not, whether you would like one of the smaller boutique style places or perhaps a very standard 3 star like the Allson ( which has excellent facilitise for the price ) near Bugis area.
