Masaya is a city in Nicaragua
From the airport you can take a taxi cab that could charge you $20-30. Also, many cities in Nicaragua have buses that take you directly to Masaya such as Granada and Managua (cost ranges from 8-15 cordobas). There are also public minivans known as microbuses that will take you from Managua to Masaya for a bit less than $1.
Also, Masaya has several churches built in the colonial period and in the 19th century. Someof the churches are: Nuestra Senora de la Asuncion, San Jeronimo, San Juan, San Miguel, etc.
Masaya is famous for a really big mercado that has great smells and everything in abundance.
Masaya has a great handicrafts market for tourists. You can buy anything from bracelets, to pottery, to machetes/knives, artwork and good quality hammocks. The market is worth spending a couple hours at.
Hospedaje Central located just a few blocks from the Artisans Market and across from Fruti Fruti. It's a small hostel in a family's home. The rooms were $4 per person a night and had a very basic bathroom and shower in the bedroom as well as a TV and free wifi. The family was very friendly and helpful. They let us use their fridge and helped us try to arrange a night tour of the volcano. Locks are provided for the bedroom but not the outdoor gate to get out of the house so you have to call for a family member to unlock the exterior door every time you go in and out. A basic but great place to stay.
