The quote really sums up the Appartments.
I stayed here for 32 nights for work. Having stayed in Mumbai at various locations over the years I have to say that I would not rate this as 5 Star. Overall the service was good and staff very friendly. Staff do bend over backwards to help you. However do take their time.
Rated the rooms noisy and not great as there is renovation going on at the appartments.
Rooms were a bit tatty. All in all stay was ok. As good as a stay can be in Mumbai during the Monsoons.

This is a nice little set of service apartments tucked away in Powai on the banks of Lake Powai. I had a fantastic view of the lush green areas surrounding the place (possibly because it was raining cats and dogs while I was staying there). The service apartments are plush and very comfy. Highly recommended for those intending to stay for short to medium term in Mumbai

My family and I have been staying at the Lakeside Chalet Marriot Apartments for about 15-20ish days and are about to head back home in a few days. However, I just had to write a review before I forgot to.

The whole apartment building is located in the same area/property as Marriot's Renaissance Hotel which is for stays less than 15 days. However, in the hotel building is the pool, restaurants, gym, spa, shops, etc which are five star material. So that's where you go for all of your activities unless you would like to use another pool which is in the Apartment building. You also have breakfast in the apartment building. Taking all of the facilities aside, now moving on to the service and rooms. I have stayed in everything from traditional Inns in the USA during road trips to some of the world's best hotels including Ritz Carltons, Hyatts, Four Seasons, etc. However, the Lakeside Chalet Apartment's service is up to the par, if not better. Their service was so friendly and quick that it really made it feel like home. Everyday during breakfast, the gentlemen downstairs already had knew what my wife, daughter, and I wanted. You would see the manager and other Marriot people caring for the little kids as if they were their own by being attentive to them and even looking after them for 10 minutes with joy. Bravo.
Moving on to the rooms. I stayed in both the 2 bedroom(had guests) for a week or so and now I am in a 1 bedroom apartment. The two bedroom is quite spacious, about 1000sqft with 2 nice bedrooms(master+regular), two bathrooms, kitchen, living room, and a walk-in closet in the master bedroom. The 1 bedroom has a smaller living room, smaller kitchen, and a regular sized bedroom and bathroom. Both the rooms are the type of rooms of which you would expect from Marriot.
Lastly just to tip out a negative(only one) was the location. It is in Powai, meaning it is like a "suburban" and upcoming area of Mumbai. It is pretty much an hour to two hours to South Mumbai and about an 1 hour when commuting to northern cities like Santa Cruz, Bandra, and Juhu. My family and I had to really think about moving just because of the location because all of our work was in the Santa Cruz and South Mumbai area. We usually had stayed in the Hyatt apartments in our 6 other trips to Mumbai but this one is up to the par and i'd give it a shot if you want an ultra-friendly, quiet, relaxing, and quality place to stay.

If you need to stay around Andhari and at the same time want to avoid the crowd and metro construction then this service apartment provides a very peaceful and comfortable accomodate.

Important consideration if you are a marriott rewards member. This apartment provides a significantly discounted loyalty reward points compared to the standard points policy accross other marriott brands and in case this is important for you then you are better off going to Renaissance Mumbai Convention Centre Hotel which is located in the same premises and offers a better quality room and dining options.
