My wife and I have stayed at the Posada Catarina five times. It is comfortable and nicely decorated. There is a fan in the room and is very convenient. Be careful when leaving. The guys at the front desk are running a scam on us gringos saying the taxi to the airport is $1200 pesos. They are getting a kickback from the drivers. Other than that (which leaves a bad taste in your mouth when you leave) it is a nice place.

Posada Catarina is very welcoming. I've stayed there twice over the last 2 years, and both times was impressed. It is a quite oasis in the hustle and bustle of the market district. The location is great - five munute walk from the Zocalo. The rooms are very authentically decorated; to keep it quite, ask for one on the second floor, toward the back. Three patios in the hotel are all charming. There is a decent restaurant where you can have breakfast. Free parking is also a great plus. Most of the staff does not speak English, but will do their best to try to understand you.

The only drawback I found was the shower - the water wasn't too hot, and the water pressure was pitiful. There were also minor problems with the toilet. For the price, however, I can't complain.

Great staff, clean rooms. They have a nice roof garden that is great for relaxing in the evening. We stayed there for 8 days. The hotel is not luxurious, but it is nice.
