Yes, yes. About 40 minutes from the airport and very safe. Lots of nearby restaurants and shops and a bunch of banks. Also not too far from Lincoln Park with an aviary and walkable to the big Bosque park.

Polanca is very nice Mexico City neighborhood - very similar to upper east side of NYC - nice restaurants and small boutiques. Has hotel area with large hotels like Marriott, etc. Close to park and museums. Felt very comfortable walking around.

Walk around two days before and you will find plenty. Casa Portuguesa, La Hacienda de los Morales, Quintonil, Chapulin at Hotel Intercontinental, El Bajio to name a few.

Here are some of favorites based on decor and food. La Unica & J by Jose Andres. Really you can't go wrong with the restaurants in polanco since they all have their own unique style and flavor.

Depende del presupuesto, valdría la pena buscar en las zonas de Polanco, Reforma, incluso Condesa, en donde hay opciones como Intercontinental y Camino Real.

Google maps will guide your journey. If walking is possible for you, enjoy the view. With bags, take a Uber. Very cheap and great availability in CDMX.

I would say it is safe, definitely one of the most upscale areas of Mexico City with high end shopping and restaurants. I do not know anything about the dental services there.

It's about 7 km, there are good safe buses that run on Reforma avenue and that would take you very near to downtown, just get down at Reforma and Juarez an walk east towards fine arts palace, it's a nice 10 minutes walk. Main historic downtown area is very safe, but still I would suggest visiting it during daytime hours.
