Let'a make this clear, you don't want to spend a lot of time in SAN Pedro Sula since it's not such an interesting city and it has safety issues.
If you do end up here, Blanca, the owner of Dos Molinos will make your stay as easy as possible (book a safe taxi from airport for 15 USD, get up at 4:00 am to put you safely in a 100 Lempiras taxi to the bus terminal so you can catch the first bus out to La Ceiba to board the ferry at 9:30)
This was GREATLY appreciated.
The room was a bit darkish and musty but clean sheets and comfortable bed. AC, TV, Wifi and hot water all worked fine (not that you would need hot water in that heat !)
For the price it makes a very nice and practical overnite stop . It's also possible for Blanca or her cousin to cook up homemade food for you.
