We stayed three nights at Giovanna's place. What an amazing location! We walked everywhere, it was quick to get to from the train station. Giovanna was quick to respond and check in with Judith was a breeze. They were both very friendly.
As many other posters said -- its a great location in the plaza so it is loud at nights and early morning, so bring ear plugs. We did so the noise did not bother us at all. Highly recommend this place for people that want to be in the central of it all.
