If you are planning to come to EPC this season, I recommend you to stay at Finca el Caminante. Here you have the cheapeast prices around and you can get to the climbing areas in a 20 minutes walk. Also you can get to the town walking 25 minutes.
Finca el Caminante includes different options for you to stay. There are many camping areas for your tent and also, if you want to be more comfortable, you can stay in the hostel in a shared bedroom, in the glamping or the private rooms, if you want something more private.
You can find all the services here: water, showers, wifi, kitchen, laundry, the climbing guidebook.
