We visited Colonia de Sant Pere for two weeks and had a wonderful time. The mediterranean is only minutes away and withing 15 minutes we reached a nice sandy beach with crystal clear water. The house is located a bit outside from Colonia but the 15 minute walk into town for dinner is great and you can choose between various restaurants/bars. There are also two supermarkets where you can get all you need.
The house is very well equipped and despite houses around nobody is able to look into it from outside.
We can clearly recommend the house and the region.
