I have booked a vacation rental in the rainforest close to Rio Grande (the address is Rio Grande (El Verde?). I have no driver's license, so renting a car is not an option. Is there a taxi company in Rio Grande that will take me there? Host says Uber goes there from the Airport, but a) I'm not coming from there and b) I'd like to have a plan B. It seems I can get an Uber from San Juan where I stay first to Rio Grande itself, but I worry about getting to the vacation rental inside the Forest.
