We had a great stay at Antonio's. The appartment is more than big enough for two and has a great bathroom and balcony.
My friend and I rented a car, which I would really recommend because the streets with restaurants of Cala d'Or and Cala Ferrera are pretty touristic. With the car we went to great beaches and towns in the neighbourhood (cala sa nau, santanyi, puerto petro etc.). Also there are enough free parking spaces in the street of the appartment.
From our balcony we had a great view of the beach Cala Ferrera, which is also a very nice spot!
We would really recommend staying at Antonio's place. The communication was great and Antonio was a friendly host.
