While the views overlooking the sea are stunning, the other side of the apartment is less than 20m from a busy train line. The trains are frequent, approx every 10 minutes, and very loud. They only pause is from 12:30am to 05:30am. Unfortunately the bedrooms are on the train line side and it kept us awake. The side terrace with the large dining table also overlooks the train line so we couldn't use it. It was simply too loud.
On top of that, the apartment is tired and badly needs updating /maintenance. Examples : the tile grouting in the bathroom is damaged and has mildew, the kitchen surfaces are greasy because the extractor fan filters are so dirty they no longer work, the couch is filthy and torn in places - it badly needs to be replaced, the airco is old and not strong enough to cool the entire department, two of the wooden outdoor chairs broke as soon as we sat on them (and we are not heavy...), insufficient glasses, chipped crockery etc, etc.
We expected a much higher standard and felt cheated and very disappointed with the price v quality.
Luckily Sitges and the surrounding area is beautiful and we enjoyed exploring both!
