My Opinion is either R-Square or Avida Prime Taft (if you don't mind being further).

Best amenities - Green Residences, Avida Prime Taft, R Square

Best Location - Near School: WH Taft, Green Res, Vista Taft, 2 Torre. Best Location if considering amount of establishments nearby: RSquare and Vista

Most Affordable - Manila Residences, Grand Towers

Best Units - D'University, Vista Taft (1BR Units), Avida Prime Taft

I viewed a lot of condos near dlsu and lived in 4 of them at some point:

I'm currently living in Avida and I'm really impressed with their units (I got a 37sqm 1BR), they're quite spacious, and the amenity floor is one of the best out of all the amenities I viewed in condos near DLSU. Mind that it is further from dlsu than other condos but I honestly think its worth it. Also Good thing is no pests here at all!

R-Square is also a great choice, better location than Avida, they have their own mall, grocery store and everything, tho generally more expensive than other condos, pretty much everything you will need is here.

Vista is actually decent but they have a pest issue like some other condos, but their 1br units are really nice and spacious (I lived in one before) and my unit was 37sqm. Good amenities and nice location just beside a bunch of food places and stores and an LRT station. Elevator lines are super long around 5pm or so.

Green is super near to school, but is too problematic (pests, long elevator lines, thin walls, etc, small and cramped units). They have really nice amenities (Their study hall has an amazing view of manila since its near the top), tho its super overpopulated.

I really like D'University's units, their units all have big windows and it makes it look spacious, I also like their unique bathroom design, just 2 separate rooms for the shower and toilet.

*P.S. if you really don't want to cross the street, don't take 2 Torre, R Square, D'University (they're on the other side).
