First off, the house is nice and the staff are great. We had a nice time here for a few days. We were visiting with 14 family members for a birthday celebration. Unfortunately, my family member was bitten by beg bugs on her legs, abdomen, and face. The sheets had red/brown stains suggesting the presence of bed bugs and the mattress had large dark brown stains also suggesting bed bugs. My family member went to the doctor who confirmed the bed bug bites. We left the home after discovering the issue and needed to stay in a hotel. The owner of the home did not take responsibility for the bed bugs and blamed the beach. The owner hired an exterminator to visually inspect the property and they did not see any bed bugs. That said, it may have been an early infestation with a few bugs which could be extremely hard to find visually (is what our doctor said). Plus the mattress and sheets showed evidence as well. Ultimately the ownership did what they could, but we did not feel comfortable staying at the home and needed to leave. The owner has so far refused to give us a refund despite the evidence from the doctor, the dirty sheets, and the mattress. They said they would fumigate the place (they also need to replace these mattresses).
Overall we were having a great time even if Jaco isnt the best spot in Costa Rica (not the prettiest beach and downtown is not tourist friendly), but the house cleanliness left my family member bitten on her face and us stuck in a hotel.
