This is actually a lovely property, quiet and relaxing in the shadow of the Arenal Volcano. My issue is that I was double charged for my stay at the end of March. I was a single traveller booked for 3 nights. On my second day, the hotel staff asked that I do them the favour of relocating for a night to another hotel close by. They offered the compensation of a night for this. I agreed, packed up my stuff and walked over to the other hotel, (it was almost the same property and apparently owned by a sibling). Then i packed up my stuff again and relocated back to the Montechiari.
I had to check out early as I had an early transit. The receptionist hadnt arrived yet, so it was the owner (as I was told) who checked me out. I was told there was an additional charge of 90 dollars (USD) that I had to pay. I paid in cash but she couldnt find the reciept book. And then my transportation arrived and i had to leave. I had pre-paid through Expedia, including all taxes and I had not outstanding balances.
I tried to solve this with Expedia, but after weeks, Expedia was told there were no additional charges.
My best guess is that I was charged the fee for the other hotel room and for doing Montechiari a favour when they overbooked.
Its unfortunate, it could have been a great experience, but it was soured by the hotel's staff/owner trying to cash grab.
Just a cautionary thing to be warned about when booking with this hotel.
