Hi Suzie,
I am on Terrazas the island, and our maintenance charges are quarterly, between €320 and €340. The entrance to the island has nearby a skeleton being completed which should be finished in 4 to 6 months, however we are here at the moment in Block 164 and no intrusion at all.
I must say that is an excellant choice on a top floor corner unit, this is a lovely resort, not overcrowded, fantastic views, great pools, and people are really friendly
best Regards
Kevin & Debbie
