Caguas is a great area as it is pretty close to the mountains and weather is a bit better. There is a town next to it called Gurabo that may also want to check out as they built very nice communities there which get you a bit away from the bigger city life like Caguas. I have friends that live there and don’t even mind the commute to work in San Juan every day because of how great it is there. I may be heading back in September fo a couple of days for business. Let me know if I can help you in any way!
