The hotel has a great location near Jingshan Park and The Forbidden City.
We took a taxi from the Capital International Airport to the hotel, and it's good to know that they taxi driver will charge you for the fuel and the toll gate plus the amount the taximeter says.
At the hotel the personnel is very helpful, and while their English might not be the best, if you give them time and is patience it'll work out. Patience is they key.
Breakfast at the hotel is something I recommend, it was really good, we ate it until we were stuffed before we headed out on out adventures.
The only downside we had during our stay was the showers sewer. It didn't suck up the water and eventually the water would flood over and ironically the sewer outside the shower works best!
Other than that our stay was enjoyable, we had no problems, internet worked just fine even though it was slow at times, but that's a Chinese standard.
I greatly recommend this hotel, it's located on a backstreet, and in the evenings you can buy cheap food from the local booths.
There's a small convenience store around the corner, and the subway is 20 minutes walk away.
The subway is indeed the fastest way to transport yourself while being in Beijing, and it's cheap too, though that means a lot of other people will ride too, but if you don't have any problems with tight and warm environment, I suggest you take the subway, it's worth the money and time!
Hope you'll get an enjoyable stay in Beijing at King Parkview Hotel.
