San Juan Travelers' Reviews

4San Juan a charming place

Really enjoyed a few days in San Juan before taking a cruise. People were friendly, food was great and Old San Juan had so many interesting places to explore we just ran out of time. English was not as prevalent as I would have expected but we did just fine. - Allan  Apr 12, 2019
4San Juan is sunny, warm, and beautiful

We loved the San Juan po0rtion of our trip. Old San Juan is beautiful and vibrant with lots of little shops and things to see. Most of the people are very friendly and approachable. Some only speak Spanish, which made it difficult to communicate at times. Otherwise, it was very enjoyable. - Ron  Mar 20, 2019
