My husband and I stayed at the Lost Iguana in La Fortuna for 3 nights.
Room- out room was very spacious and had a beautiful view of forests and the volcano. I am a big reader so I loved how the room included portable reading lights. The room also had air conditioning and a dehumidifier.
Location- we loved that the hotel is in the heart of the forest. We saw toucans around the property. The nature walk on the property was great. It is a pain having to drive so far into La Fortuna, but it's a safe, well lit drive. You definitely need a car because many pick up services charge extra to go to Lost Iguana.
Service- the service was the only area that was somewhat lacking. We called for ice and the front desk forgot about us. Had to call again. The restaurant had very slow service at dinner. Worth driving into town for dinner. Breakfast was delicious. They charge for local phone calls, which we didn't know until we checked out. The front desk was friendly but not out of their way helpful.
