This accommodation is very nice, clean, and offers great views of the city. It was a nice amount of space for our family of four. All three of the beds were extremely comfortable, with nice linens. The bathrooms also all had small hotel-sized bottles of soap, shampoo, conditioner and lotion, which were nice touches. We did have trouble with the hot water heater during our stay, which was certainly unexpected and out of Guillermo's control. He was incredibly apologetic, stopped by personally to offer his apologies, and also offered potential solutions. I wouldn't anticipate this happening to anyone else, but I appreciated the way Guillermo handled the situation - it shows he really cares about the comfort of his guests, and wants everyone to have a wonderful experience staying in his place.
The building itself has many amenities that are available to the guests, including a spa/sauna, children's playground and play area, pool (not indoor but covered by a large tent), and gym. The building is also very safe and secure, with 24 hour security at all entrances. It is also above a shopping area, including a very nice 24-hour grocery store. The location is within walking distance of several museums, restaurants, parks, and high-end shopping. It is in a very busy area.
One thing to note - since the location of this apartment is in a busy area of Polanco, there is quite a bit of traffic noise. If you are a light sleeper, it might be best to wear ear plugs or bring a sound machine to help block out some of this noise at night.
