I have played a few rounds against bots and walked around the map without bots. I second Text_Fish's review in every point. Some things I want to mention:
1. Performance:
The map, although it is small and only small areas are visible at once, does not run very well. Did you optimise it? I did not test with mat_wireframe on, but somehow I was getting rather low FPS, even alone (50-90), while a Valve standard map will run with over 200. Of course your map is rather detailed, but the performance is quite bad in my opinion. With a few bots added it was almost unplayable.
2. Visuals
It needs some more contrast. A few harsh lights would be nice, because all your nice detailing is washed out into a grey mess. It looks too much like MW2
I suggest you add some spotlights. Some lights to guide the player would be nice, too. For example some kind of lightbulb at the stairs and at the ladders. Otherwise players new to the map might be turned off quickly.
Also, I think you used env_lightglow on your lights? It looks strange, to wide. Perhaps a sprite would serve the purpose better?
For better orientation, you should also use more obvious signs to the bombsites. The map is quite a labyrinth. Without looking at the minimap the whole time I once ran back to my T-Spawn without even noticing it.
As you use a shanty theme, I think bright yellow spraypaint (for A, for example) and bright pink spraypaint (for B,f or example) as hints would serve the purpose very well.
Otherwise, the map is looking great. You made great use of the props and textures.
3. Gameplay
As Text_Fish mentioned, the bots tend to get stuck. Otherwise I guess it is balanced nice enough. When I let the bots play against each other sometimes CTs won, sometimes the Ts won. Good enough.
I really like it, but I think it has much more potential
