Our stay in Martha's place was very relaxing. It is centrally located, walking distance to the zocalo (central square) but on a quiet street. The bed was firm and comfortable, and having a mini fridge and microwave was practical. So many places to eat, but seeing and being in the zocalo at night and on a weekend was amazing. Families with their kids and dogs, old people, young people, zocalo performers, priceless! Oh, about safety; we felt ver safe. There is a police presence everywhere, and we walked miles all around, never feeling uncomfortable. Highly recommended stay.
