I would try your request on the expats in Managua facebook page. You might get a better response. Keep in mind that most people do not like Managua and that includes Nicas. I like it but most people just hurry thru. Managua can best be described as very hot with 24/7 gridlock. Some parts are very poor and some are rich. The smaller towns are much easier to navigate and generally more livable. Nicaragua is a small country so travel is fast to and from most places.
