Gerrits Place is very nice to spend your vacation in Porto Cristo. It is clean and in perfect range to the city beach. If you are a Group with about 8 to 10 people, the hole casa would be a great option for all of you. There is enough space ;). Gerrit is a very kind and polite guy who will give you any answers for all kind of requests you might have. He was answering immediately. The next bus station is also not that far away. So you can take line 441 an check out lots of great places with no need renting a car anyway.
And a short hint: don't miss visiting Cala Anguila ;).
Special thanks Gerrit! Maybe i'll come back next year :)
