I have come to stay at the Pension Castil through a workaway program for 1 and a half weeks. I get to work with Eva (the landlord) every day (painting and refreshing other apartments.) I have to say that this has been one of the greatest experiences I've had. I spend a lot of time in the Hostel. My bed is comfortable and I sleep well at night (even though it is hot here in Granada in the summer... there is a nice breeze that comes through the windows making it very pleasant.) I share a 3 bed room and find it to be basic but spacious enough. We have a sink in room and a shared bathroom. Everything is very clean (Eva makes sure to keep it that way.)
It is the PERFECT location in Granada. You are a very easy walk away from most everything in the city. It is very easy to leave to explore the city and come back and rest. Even though it is in the center of the city... there is not as much noise as you would expect (although by habit I do sleep with earplugs.)
Eva is one of the greatest people I've ever met. She holds the line, but is also very giving and generous. She has helped me out immensely!
If you are looking for a budget place to stay without all the bells and whistles, but within the heart of downtown Granada... this is the place for you. I would HIGHLY recommend it! I will be coming back for sure!
