• 225 N Calvert has a pool on the roof. It's pretty nice. It is also accessible for wheelchairs. Nice view of east and southeast Baltimore, including a bit of the harbor.
• 300 Saint Paul Place also has a pool on the roof. It is smaller than the pool at 225 N Calvert. It is not accessible... I don't know what people were thinking when they converted that building from offices to apartments. I want to say it is an easterly view. I didn't like the view as much as 225 N Calvert.
• Someone already mentioned the pool at 500 Park, on the 3rd or 4th level. It's about the same as 225 N Calvert, but 500 Park is more resort-y and 225 N Calvert has the city view that makes it unique. The 500 Park pool is also accessible. You have a view of Park Ave and a courtyard backing up to some of the apartments in the building.
• Luminary at One Light has a really nice pool. I don't know what level it is on, I only toured the building. I do not recall if it is accessible. I remember being impressed by the pool area. The common areas reminded me of being in a treehouse? It was cool and different. Possibly the best view of the 4. It's been a while, cannot recall.

Basically many of the high rise buildings are likely to have a pool.
