We had a wonderful stay at hostal marblau. The location of cala figuera is away from main city from all the hustle and bustle. Although the car is most convenient option. If you don't have one, I recommend taking a shared cab which is much cheaper than private taxi (look for suntransfers.com).
They were continuously in touch with us before our travel date and answerd any questions we had through airbnb message. We reached quite late at night but check-in was very smooth. The room was extremely clean and all the equipments as well as the AC was working perfectly.
The spar convienence store below the hostal is small and a bit expensive but will be enough for any meals or water requirements.
The location is very convenient and you can reach good restaurants on foot and the fishing bay in 2-3 mins by foot. Cala figuera itself doesn't have any sandy beach. But cycle (Redstar tours) or car can be rented from nearby rentals and the sandy beaches can be reached quickly. I recommend cala santanyi and S'amarador which are quite nice.
The hostal reception was pretty helpful for recommendations and any questions you might have.
Overall a solid recommendation 😊
