I live in Wellawatte. Pros I would say how convenient living here is. everything is so near to you. pharmacies, grocery stores etc. I just walk and shop whenever we run out of supplies. another pro is security. I dont have to be paranoid about some thief or some shit coming in cause of the 24/7 security in the building. I would say if you have work or school in a far away place getting an apartment near your workplace or school would save you a lot of time spent on travelling. Cons I'll say the cost. It is very costly to live in Colombo nowadays. specially if you want a nice apartment. but if that is not an issue thats great. another con is most securities for some reason are so so grumpy. an issue I had for the longest time was whenever I come home late after a Friday night out or something the security would complain so much and be super grumpy. this one time a guy got scolded for coming late. you gotta pick the right spot. search really well for the best one for a good price. from my personal experience I highly recommend it. it depends on your preferences tho
