Very good place. It's a little away from the town (Cala major) so very calm and away from the bustling crowd. At the same time the town center and beach is just 10 mins walk. One reason for not recommending high on the location is because we were with a toddler in a pram and the walk is little uphill.
The house was very clean and Grigory even managed to get us a steamer in the kitchen and he was able to give us an early check in. So we felt very good walking into the house. On 14th floor the place is well lit and very well ventilated with big windows in living and kitchen.
Lastly Grigory spent good time familiarizing us with the place and neighborhood. His recommendations of Cala cometesa beach was absolutely what we were looking for in Palma.
