First of all: Isabella is a wonderful host who always replies right away and tries to fulfill every need.
We had a very nice stay at her house. It is nicely decorated and very clean. The place is really close to the wonderful sand beaches in the southeast of Mallorca and in a more touristic area (Cala d'Or). But since the house belongs to a gated community you won't find many tourists around (instead residents from all over Europe) but still, it is a rather open community. So if you are looking for something secluded and private (which we did, without really thinking about before), this might not be your choice.
Restaurants and supermarkets are close by so you can enjoy a barbeque-dinner on the terace.
You can definitely go there without car and just enjoy the beaches in walking-distance but I would still recommend hiring one so you can see more of this wonderful diverse island.
