Commenting 5 years later on hindsight... I-Santorini probably is the best investment we made. There's never short of people wanting to rent as this location is super popular with expats. We rented to an expat family, and was quite surprised because the husband was actually working in Bayan Baru. But they still prefer to rent in Tanjung Tokong because of their kid's education, somehow they think the international school in Tanjung Tokong is better. And even till today we still get non-stop calls from agents wanting to rent units for expats, korean, chinese, japanese etc.

unit size is standard 850sf, price is around 530psf and rental around 2k+/monthly, carpark can be separately rented out as well. You have to get block A to get a good seaview facing Brezza condo, but last I heard they are going to have new development near Brezza, so the sea view may not last.
