Visiting Nica Soon Would Like to Talk to Expats or Locals for Advice

I was in Granada yesterday! In Leon now. You can find someone to take care of your father here I'm sure. They have a private hospital and a public one. I don't know how much a private nurse would cost but costs here a reasonable with almost everything.
One thing I would bring to your attention is that hardly anything here is handicap accessible. This means that he won't be able to roll a wheelchair down the side walk and cross the street in one alone. If he walks with a cane he can move around the city as there are many people here who walk with canes.
You can hire a translator from any of the schools. They are expensive if you hire them through the school and I would suggest getting a young assistant that can speak both even if it's broken Spanglish. For example I speak both but I have people that work for me that can speak both as well. A school will send a translator for $30-50 dollars a day or u could hire an assistant for $60 a week. They could also double as someone who could do all your shopping and organizing your travel for you. Well worth the money.
Many places I go, the price changes as soon as they see me get out of the car. When they see a foreigner the price doubles. My assistant negotiates for me and then I get out and pay. She saves me more than $60 a week so it's well worth the money. Things to consider. If u are looking for a wheelchair friendly area look in Fatima. They actually have decent sidewalks.
Hope this helps.
