We spend 3 nights at the Impiana and loved every minute of it.
We arrived by car and the Hertz city office was within walking distance, returning the car was easy.
We had a comfy room with a good view of the Petronas Towers and the pool.
The breakfast buffet was great.
Locations wise its perfect, especially if you are, like we, a Kuala Lumpur first timer.
There is a aircon walkway between the hotel and the Petronas Towers, the monorail and
the Pavillion mall with its restaurants and bars.

Our room had a good view of the infinity pool and a little of the Petronas towers.
Breakfast buffet was good.
The hotel has an air-con link to KLCC, Pavillion mall, etc.
Alex, a Filipino staff, was very attentive to all our needs.
Saisaki, a Japanese buffet resto, is just nearby.

I accompanied my husband on a recent business trip to KL and stayed at the Impiana KLCC for 2 nights. The Lunar New Year decorations were still up, and the hotel lobby looked gorgeous, all decked out in red. We both loved that Impiana KLCC was in the center of all the action. For my husband, the hotel's location made it accessible for business meetings; for me, what worked was its proximity to the shopping malls (10 minute walk to Suria Mall, 5 minute walk to Pavilion Mall, Lot 10, Fahrenheit). This is a 4-star hotel that is well-priced, considering its central location. If you check Agoda, Expedia, etc., you'll find that other hotels located along the same street (Jalan Pinang) and/or within a 2-kilometer radius from Impiana are priced from 20%- up to 100% higher. Aside from price point, another big plus is that this hotel is connected to the elevated, fully air conditioned walkway that allows you to walk, in comfort and safety, to tourist attractions like the Petronas Twin Towers and Bintang Walk (thru Pavilion Mall). The only drawback was the lack of warmth of the Front Desk personnel and the Concierge, which we found odd since they do most of the customer-facing work. This was in the contrast to the exceptional service orientation of the housekeeping staff and the bell boys. Overall though, we enjoyed our stay at this hotel and will stay here on future trips to KL.

Location wise it is good . Located just on the back of Petronas Twin Tower. Rooms are big enough and nicely furnished. When we were there , hotel parking was closed for construction . We have to park quite far from hotel . Opposite to hotel there is a huge construction site giving a noisy n ugly view.Area is day & night jam due to office goers . Taxi in this area will never use meter. Be ready for rip off by taxi drivers.
