We used Grandpas Hotel as our base for visiting Irazu volcano and Cartago. It's a little bit a drive to the city, but fantastic location for Irazu.
The cabins are very clean and comfortable. Good beds.
Service at reception and breakfast was impeccable and super-friendly.
Beautifully manicured hotel grounds outside of town on highway 219.
We could hear some street noise from the highway in our room, but it wasn't bothersome.
