We hate to be negative, but feel we owe it to future guests to be honest.
First it is important to know that you will not be staying with Sigifredo, but rather his niece Carla. She is lovely, but it can be confusing and off putting when you don't know who you are staying with.
Also although the listing is in English, I do not believe it is suitable for anyone who is not proficient in Spanish. We failed to receive any address or directions prior to our arrival in Turrialba, then spent a stressful 2.5 hours trying to find the place with piece meal communication.
Out of desperation, we actually ended up contacting another AirBnB host to find directions. She was extremely helpful, and proved that it was possible to provide sufficient direction to the address. Although by this time we had managed to make phone contact with Sigifredo (the number listed on the profile is incorrect) and locate the property.
The property itself was as described and Carla was very helpful and friendly in booking tours for the following day. Carla and ourselves managed to communicate with little drama via (SENSITIVE CONTENTS HIDDEN) Translate.
Once we arrived it was a generally positive experience, but the arrival process was a shambles which tainted our trip to Turrialba.
