I was a bit worried from other reviews, but this stay was SUPER clean! I'd like to think I have high cleaning standards. It was our favorite hotel at Santorini. The jacuzzis are semi-private--they're near one another outside, close enough to where you can hear conversations, but each room gets their own. The Superior room can sleep 3-4 people--you can turn the couches into 3 beds on request. (1 queen, 1 twin, 1 twin). The hospitality was incredible, and it felt really good to stay here. I wish I could've stayed at this hotel the entire time we were at Santorini. It had a smart TV with Netflix, Spotify, etc. which is surprisingly hard to find in Santorini. The location was close to the main street, about a 10 minute walk. Beds were comfortable. Easy to get in contact with host to get new towels, sheets, and random items such as bottle openers. The owners of La Casa de Caldera provide tons of info and options for things to do, such as massages, horse riding, and places to go. Me and my two friends loved this place. For context, we also stayed in Perissa and at another luxury hotel in Oia. I will say that the shower does get water everywhere in the bathroom, but that's the only negative, which really isn't that bad!
