we had a great room with a view of the volcano and lake.
Staff was very friendly, rooms were clean and food was good.
I would recommed it and hope to return one day

During our stay we had master suites (really just very large rooms) with perfect unobstructed views of Arenal volcano. The view was amazing, particularly at sunrise (I didn't even mind being awake at sunrise - the view was that good). The pool was small but again had gorgeous views and we ordered some great specialty drinks from the swim-up bar. Breakfasts were good as well.
The hotel is more than a half-hour drive from La Fortuna on a badly-maintained gravel road, so it isn't a place to go if you want to spend your evenings in town, but unlike the La Fortuna hotels it's on the side of the volcano with lava views and it's truly peaceful and beautiful. The National Park entrance is between La Fortuna and the hotel but closer to the hotel.

Unbelievable if you want an entire view of the volcano ALL DAY LONG. We were able to monitor the volcano's activity from 6am until late at night and see eruptions from our bed.
Literally your view from your sliding class door/window is entirely filled up by the volcano.

ROOMS/FACILITIES:
Stay in the Jr. Suites. Good view, good price.
Hotel is the closest hotel to the volcano.
The restaurant has tasty fish, some of the best pasta I've eaten and has a view of the volcano as well.
Pool + Hot tub, my husband used the hot tub but said it was not as warm as the thermal pools in Arenal.
Internet was on and off, so was the TV but that is a given since you are far out from the town. There were tons of bugs that fly in your room at night, but again, remember you are at a volcano so what can you expect. Mattress was a bit worn down, but we simply flipped it.
Bathroom was decent, a bit beat up but decently clean.
Downfall, it's far from the town so you either eat at the hotel or at a local food joint down the road. But again, can't stress enough, the view makes it all worth it.

PRICING:
Pretty good value for about $85/night during low season

WONDERFUL VIEW - we saw tons of volcanic eruptions and we didn't even go to the national park!!

My husband and I traveled to Costa Rica for the first time and stayed our entire visit (5 days) at Linda Vista. We stayed in a Master Suite and could not have asked for a better view of the volcano and the nightly show that it put on.
I didn't find the food to be too bad in the resturant and it sure beat going back into town to eat. If you are a coffee drinker and need more, just ask the front desk as they are happy to give you more. My husband and I would sit out on the balacony at night, watch the volcano and drink coffee.
Bernardo, the hotel travel guide was awesome, he took a few of us out one night to find the famous Costa Rican Tree frog, and of course he found it. We got amazing pictures. Bernanrdo, also knows a lot about the birds in the area and is great at spotting them, and pointed out several birds to us and at one point stopped for us to see a Tucan.
There is a Horse Back riding tour not far from the hotel that is not advertised as much as the La Fortuna one, but is amazing as you ride way up the mountains behind the hotel and hike down to a private waterfall.
I can't say enough about this hotel, the staff and location, it was an AWESOME trip.
