Karla's place was good but not the best. The bed was comfortable, storage was provided for luggage/clothes tea and coffee were available for you to prepare if you wanted. However, it was a bit far from the tourist areas especially since I preferred to walk to also see the architecture instead of taking the metro everywhere but it was close to the metro/bus if you don't care much for the architecture. I also had issues contacting Karla on the day of arrival, I had sent her abur 6/7 messages and didn't get a response from her at all but I showed up thankfully she was there to get me settled. Overall, good experience.
