Sorry for delay in replying
Sorry I really am pants at replying about your questions about Siesta I must check this forum more often!
I absolutely adore Santa Eulalia have been going there for over 15 years, I had a timeshare at Es Puerto, but have had to give it up as the maintenance has outpriced itself.
So for me getting a place as close as possible to Santa Eulalia was essential, hence Siesta, next best thing. We only have a tiny place as we can't be over there permanently yet, due to our business commitments in the UK, but its lovely and its ours for our weekend retreats or longer when we get the time. Maybe in time we will be able to afford to upgrade to something bigger, but for now its paid for and its our own little piece of "living the dream".
We are low down in Siesta fairly close to the river and the town of Santa Eulalia which is ideal. I think the views are beautiful higher up the hill, but personally I couldn't cope with the walking up hills all the time! Yes there are some houses and apartments close together, but it will all depend on the money you have to spend as with everything, the further up you go the better the property with some fabulous villas which will give you all the space you want.
Have a look on the google map satellite view, it allows you to get in fairly close for a good look around.
For me being close to a pretty town with good acess with public transport (as can't afford the car hire in the summer months) with good restaurants, bars and shops that wasn't club central was a must. The beaches are nice, and the Ferry can get you to others.
In the 15 years I have been going there, Santa Eulalia has always remained true to itself and I can't say enough about how much I love it there.
Can't wait to get back over.
p.s Just spoken to Bob again now, he is really very helpful you won't go wrong in using him for your house purchase.
Good Luck
