This property is 1 mile from the center of Sitges, so if you plan to walk in to town every night for dinner and cocktails, bring good shoes. The walk is gorgeous, along the coast line and past some great views, well worth it. The location being away from town means it is quiet if you want to call it a night and go to bed before 2am when the town center gets quiet.
The pool is really nice when you want to cool off, or use the outdoor pool shower to rinse off the beach sand. The best part of this location is that it is right next to Balmins beach (the nude/gay beach by the way). There is a cafe here at the beach as well, if you want dinner and don't want to talk to town.
Anyway, the apartment has an AC but its in the living room so you have to let it run a bit to cool down the whole place. It does eventually. I never had a problem. The extra room with smaller beds would be perfect for kids but I travelled alone so never even went in there.
Coffee maker. Laundry. Fridge. All the modern conveniences you don't get with a hotel. Just remember to bring some beach towels, and buy an umbrella. The sun gets hot in the med and you'll need em.
Very much recommend this location. I had a great stay.
