The place is located in Santa Marta, approx 30min walking from the beaches in Varadero. You might be able to get a bike from the host, I am not 100%sure.
The rental has its own access, kitchen, bathroom and bedroom.
The host is very kind and helpful.
I was able to use their internet for a reasonable price (in cuban terms) without having an internet account.
Probably the only frustrating things were the mosquitoes and the lack of toilet seat.
I would recommend it if you are on a budget.
