My family and I are going to Nicaragua for a month at the end of the year. I'm thinking of renting a house either in Managua or Carazo, as we'll probably be doing a lot of sightseeing (Granada, Leon, etc), but with two boys ages 6 and 12, we'll probably will have to hit the beaches as well. Our budget is not high, so I'm looking at something affordable. Any suggestions? I also want to visit Esteli and Somoto, but I'm thinking only for a couple of days (not many beaches there).
