Los Cuatro Tulipanes makes you appreciate Casco Viejo's UNESCO designation as a World Heritage Site. What a beautiful and elegantly restored historic property! Hopefully the ubiquitous renovations currently under way in Casco Viejo will rise to Los Cuatro Tulipanes high standards. My wife and I spent 3 wonderful nights there in August, and we were especially pleased with the comfort of our apartment and the quality service of the staff. Ivana took great care of us while we were there, and we would highly recommend Los Cuatro Tulipanes to visitors looking for a great experience in Casco Viejo.
