My wife, 5 year old daughter and I stayed at Isla Verde for just one night prior to flying out of the San Jose International Airport. We booked it on a whim, and were very pleasantly surprised by this hotel!
The hotel itself is quite lovely, with the open atrium, clean simple lines and colors, and amenities (like an attached Asian restaurant! Yum!) and workout room. We stayed in a Superior room in the new wing of the hotel. So modern. So hip. So comfortable! The beds were some sort of amazing Simmons mattress--sort of like a Tempurpedic, but better!! And the bathroom was awesome with the rainshower shower head and beautiful simple design.
The free breakfast in the morning was simple, but tasty. The coffee however was not so great. :(
So, overall: Thumbs up for comfortable, stylish accommodation for a great value! Not a great fit if you need/want something to "do" while relaxing at the hotel. There's the workout room, but with no pool or hot tub, that might be a drawback for a longer stay.
