the hotel is very nice, the location is great (in the historic center of mexico city) and the staff is really friendly and helpful. we were impressed they speak english because in mexico people don't speak english at all. they helped us organize a tour in teotihuacan as well and the driver was very informative and knowledgable. the hotel restaurant is beautiful but the quality of the food is average.

I received good cooperation from the hotel staff - Rooms are quite spacious - those overviewing the main street are a bit noisy during the week - Close to all important business and touristic places - Rates were in my view quite competitive. I will return to that hotel if I will visit Mexico again -

They have a very nice restaurant at the ground floor that offers delicious tasty breakfast-

Wife and I spent 5 days there. For 2 people it was good enough.Were on 11th floor, good view.Bathroom a bit crowded, but ....Hotel staff were very pleasant,breakfast was included, very good way to start day.They even brought us a small cake for our 42nd anniversary.Close to Paseo de Reforma, near many sights, able to walk to Anthropological Museum, Art Museums, and to Chapultapec Park.
Felt safe the entire time we were there.

The main reason we chose San Marino was because it said it had a kitchen in the room. The 'kitchen' was actually a fridge, kettle, microwave, and a hot plate that didn't work. There were bowls and cutlery, but no pans or cooking utensils. Sort of defeats the purpose of having a kitchen.

PROS
Good location, in the 'better' part of Mexico City. Subway is just under a 10 minute walk away.
Lots of pay TV channels.
Free internet.
Gym was pretty good-free weights, several cardio machines.

CONS
The kitchen was pretty crappy.
Our room key wouldn't work and was replaced 3 or 4 times, and still wouldn't work. We ran up and down between the lobby and our room. Eventually they gave us one that worked, but it took a while-and no leg work from the staff.
The internet was often very slow and dropped out-I think the computers were ancient.

It was well-priced, I just wish the kitchen had been better.
