Hi Itsybitsy, welcome to HT!

Sorry, can't help re wifi but I can direct you to the reviews for the Cost Sal apartments HERE in case you've not yet seen them I stayed here several years ago and our apartment was HUGE!

Not sure about the WiFi in the area but you could purchase one of these prior to going and it will find it for you if there is any
