After looking at rooms in four hotels I went with Hotel de la Soledad.
Wow, I am so glad I decided to spend a little extra money to stay at this fabulous hotel. The building was built in 1701 and is of the classic baroque architecture as is much of the historical central district. Just a half block from the cathedral and around the corner from the Casino Hotel where you can sit have a drink and watch the people. My room was fabulous as well as spacious and seemly very new. The staff was extremely helpful and friendly, really nice people. The price includes an American style breakfast. I had a room on the 2nd floor in the back that was very quiet and safe. Many locals come for wedding photo shoots because of the grandeur. For me it was expensive but I was glad I stayed there.
