Yo bro, me no expert so these are just my personal opinion
1) Fiorenza
>> Always pass by this after eating the Punggol nasi lemak
Didn't like the look and the narrow road leading into it.
2) Oasis Garden
>> Kinda like this one (from exterior) but my family didn't like the environment so I didn't arrange for viewing. Seems quite a lot of people selling it.
4) Palm Vista (telok kurau G)
>> This looks good actually. I'm more of a balcony/roof terrace person though :P
If you are looking at TK, can try look at closer to East Coast Road. ERL has station at Marina Parade and Siglap so good chance of a intermediate station nearby.
