10/10
I was a little reluctant to book this two-star guest house, but none of my worries were merited. My room was nice and comfortable and more clean than I have seen in even some of the best hotels I've stayed in. The property also is kept clean and everything looks like it was painted just days ago.
A hotel level breakfast with service was not proposed, but the self service breakfast was large and varied.
All in all, Antonio's house deserves in my opinion more than two stars.
Antonio himself is a nice, funny, friendly and helpsome guy with a great sense of service. If I return to Sitges I would not hesitate for a second before booking at Antonio's House.
