I enjoyed the week I stayed at Las Mariposas. It was comfortable and met my expectations. Don't expect luxury, but it was clean and quaint. It was located in a nice area of the city and just far enough away from the hectic Zocalo to be relaxing, but not so far to be inconvenient. The fact that the gate is locked at night is nice to ensure safety, but I did feel bad awaking the night doorman to let me in after hours. Still, it didn't seem to be a problem. For the price, I thought it was great. There is no heat or AC, which is probably standard, but be advised that is did get fairly chilly at night (in December).
