The photos don't lie. This place has an incredible view (right on the lake) and the interior is fantastic as well. We stayed here with our two friends from the UK and all of us had a great time. There are hikes right from the front door and when we arrived Andre, the proprietor, went through everything there is to do in this area.
The house has a living room, a full kitchen, four bedrooms, and two bathrooms. Two of the bedrooms have a double bed, one has two twin beds, and one has one twin bed. One of the bathrooms has a shower/tub and the other has a shower.
The house is located in the town of Sete Cidades which is right on the lake. There's not much to do in the town itself so you should really stay here only if you want to explore the amazing hiking and outdoor activities the surrounding area has to offer. If you're looking for great dining, nightlife, etc. stay in Ponta Delgada.
Overall, a fantastic experience. I highly recommend it!
