As a couple, we stayed in hostels in Medellin, Santa Marta, Barranquilla and Cartagena and Masaya was the best hostel we stayed in. The shared bathrooms are still getting renovated but they are modern and the water is instantly warm. The beds are uncomfortable and the breakfast was so good for a free breakfast with scrambled eggs, juices and fruits. The only thing I can think of is that we stayed in a private room below a dorm, and you could hear the people above walking on the wooden floorboards which was a little annoying. The TV in our room with pay TV was great! The Candelaria is a beautiful area of town, but very dead at night and far more dirty compared to the Zona Rosa.
