Me and wife spent our honeymoon in Impiana hotel an it was gorgeous... its really an amazing hotel, furniture is so modern and comfortable, front office desk and concierge are so helpful, and they even checked us in so early without no extra cost. Breakfast buffet is really good.
Best thing of this hotel is its position, its in KLCC and with the bridge you can access so many places in just 10 mins walking. KL tower is nearby, Pavilion mall, Suria KLCC mall, the Petronas twin tower, Aquaria,... and so many other places.
Night life in this area is amazing and bars are in less than 10 mins walk, also so many restaurants with different cuisines are nearby.
Chinatown is less than 20 mins by taxi from the hotel (always take the blue metered taxi).
Rooms are very clean and wide, bathroom is having all the toilters you could expect, TV has about 10 movie channels.
Overall, i recommend this hotel for anyone want to visit Kuala Lampur, and defiantly i will stay in this hotel again in my next visit to Kuala Lampur.
