Hi Ailsa, have you looked in the hotel reviews on this site, or another site is http://www.holidaysuncovered.co.uk i'm sure you should find some comments on either site. I personally would say Dom Pancho is more within the resort & bars than the Santa Eulalia but the latter would be slightly quieter even though still near the bars but is a little nearer to the beach. I do also believe the dom pancho has an indoor as well as an outdoor pool but dont think the other one has. Good Luck Cheers Jayjan

Dom Pancho does have an indoor and outdoor pool.
We stayed there many years ago and as Jayjan says, it is close to bars and restaurants and 5 mins walk from the "strip".......so near enough but also far enough to avoid the noise and bustle. We enjoyed our holiday there.
Santa Eulalia is not much further along the road........probably another 5-10 mins leisurely walk and quieter but also nearer the beach.
So, in the end, it depends on your main priority.......I would do as Jayjan suggests and read the reviews.
