We chose to stay at the Lebua in Dwarka to be close to the airport in order to catch a very early morning flight. But selecting the Lebua based on its apparent proximity to the airport was a mistake for two reasons. Firstly, at that time of day (6am), driving from a hotel in the middle of town (diplomatic enclave or Janpath) to the airport is not going to take you much longer and, secondly, there are hotels that are much closer to the airport if this is your most important criteria for a hotel (I believe I saw a Radisson and an Ibis along the way).
Beyond that, the Lebua has two more serious issues.
Location. There is absolutely nothing in the vicinity of the hotel. The mall downstairs is dead and has a very limited selection of stores. And because the hotel is so far out of town, taxis are far and few between. We regularly waited 15 minutes for the next cab to pull up at the lobby (and that's when we were first in line for a cab). So in case you are in a hurry, plan ahead and book a hotel car. Dwarka is a ghost town -- especially in the evenings. Perhaps give it another 3-5 years before it becomes a bustling metropolis -- which, no doubt, the Lebua is banking on by being the first upmarket hotel in that area.
Service. Yes, the hotel is relatively new and, as one might expect, there are teething problems. Sadly, however, the Lebua (a name which is usually associated with a positive hospitality experience) in Dwarka seems to have gotten ahead of itself. Only a handful of service staff are truly experienced to deal with clientele and some staff did not know their way around the hotel. More than half the items on the restaurant menu were unavailable (in which case, just present a smaller menu, rather than send back waiters each time to say that the last thing ordered is also unavailable). And, although it is new, it already is showing signs of insufficient upkeep, wear & tear.
I can see how the Lebua might be popular for corporate events where you want to make sure participants don't get distracted by anything around the hotel, but beyond that, I don't see the value or benefit of staying here. I should add on a positive note, however, that the bedrooms and bathrooms were spacious and clean, and the beds were comfortable (obviously they were new) -- so at least that has some merit.
