Off to SEPA in Costa Rica in January

I am very excited to have chosen a Home Stay Spanish language school destination for a 4 week stint from Mid-January next year.
I have zeroed in on SEPA in San Isidro de el General in Costa Rica.
We visited the area a few years ago (but for just a few days) and I loved it so much I have been itching for an excuse to return. (the weather is cooler than at the ocean - I don't do Hot-Hot well. and there is an incredibly cool river which has HUGE boulders and swimming-pool sized water pools, for bathing, Plus ceviche)

has anyone been to SEPA? It gets pretty good reviews and .... how bad can it be? I am willing to roll the dice.

quite affordable (I think). $1800 USD for 4 weeks of M-F 4-hours a day small group classes plus half-board home stay.

we'll take road bikes to explore the area's quite quiet seeming roads when we are not in class.

I am looking forward to it.
