We stayed at Barbara's place in Petra for just under a month and can echo everything that everyone here is saying.
Photos are accurate to perhaps even a bit shy at expressing the beauty of the space.
Barbara was an exceptional host, with a semi-stocked fridge (drinks, chips, wine, sandwich fixings, pasta, sauce, smoked salmon, all that is needed to make a nicoise salad and more...that was a great touch as it saved a quick trip to the market upon arrival indeed.
Petra is a great city, and the square is just around the corner, with 5-6 restaurants/bars right there and more just down the street. Really a special place in the heart of Mallorca.
Parking for us was included as we stayed for a longer duration, and was covered and easy for a compact car/medium car, larger may have issues.
We were there from Nov-Dec 2021 and the heating is located in the living room which can heat the bedroom and also the dining room which can also heat the kitchen. The main hall doesn't have a traditional heat option so there is a portable heater you can use (we didn't as didn't mind that this space was colder, we didn't spend much time here) there is also a portable electric heater in the bathroom so that was very toasty very quickly.
So...long and short...it was a great stay, amazing property and wonderful host. We would be happy to return indeed.
