Hi
We have a two bedroom with solarium on Jardines 7 and love it loads and loads.
I agree with others who say it depends what you want and you have stated that you do not need to rent it out. We are not renting out ours at present, although may do in the future. My children and grandchildren have been over and think it is fab, I have never seen the pool busy and RBrett said it is a great place to chat to neighbours. I love the upstairs apartment because we have the rooftop which is pretty private and hardly overlooked, (We have only been there once when our neighbours one side where there and it was good to chat, the other side is vacant). If you can manage with two bedrooms I believe this is the best option because when in Spain you spend more time outdoors than in.
There is a couple in Jardines 3 who will look out for your place on a weekly basis for 100 euros per year and he will pick you up from the airport and return you, I don't think it is cheap but it is convenient, the problem there would be having to buy all your groceries etc from the site shop and like all site shops whereever you go in the world, they are more expensive.
We look forward to the other shops being filled but can wait as we truly do enjoy our own peace of heaven.
One word of caution, check out the play areas before you buy, some of the Jardines have virtually nothing in their childrens play areas and others have loads, as you have two young children I believe this is quite important. Two of my grandchildren are 6 and 10 and are the right age to go and play whilst we watch them from our terrace, which of course yours will want to do when they get older.
I hope you manage to buy and have a great time in your own space.
Good Luck
