I agree with others who said it was a great apartment, and close to the airport. We used it for an overnight, after our stay in HCM, so we could walk to the airport for our flight. We stayed on a Sunday night in January 2017.
So we took a taxi from a district 1 to Bluesky. I printed off a one page map from the booking site, and recorded the address given, and the phone number in case there were any difficulties. The taxi driver managed it OK, though when he stopped we did not immediately see the apartment sign. We were in the right place, though.
Checkin and checkout was easy. It was the first rainy day of 2017, so we did not get the chance to use the pool. It looked excellent. We did take a practice walk to the airport. The route involves going around 100m along a road with mostly motorbike traffic to a gate where most of the bikes were turning left in to a parking lot. The sidewalk was only good for wheeling suitcases for part of the way, as the it was broken up closer to the gate. Using the road for this little bit was not a problem.
We also turned in to the parking lot, and went down to the far end. There were entrances in to a water processing plant to the right, but we just passed these by. At the end of the parking lot, there was a roundabout with slip roads. When wheeling the suitcases, we had to walk on a little bit of the road, but this was not part of the main roundabout. Basically we did a right turn here, and suddenly we were in the airport (arrivals level, international terminal). Not far along the terminal, there is a lobby off to the right where you can get a lift or escalator to departures. We did not check out the domestic terminal situation.
As to places to eat, there was not much - but it was Sunday, and we did not look very hard. There was a 24 hour convenience store on the other side of the building from the entrance. As the apartment is fully equipped, including a microwave, this was OK for us on our last night.
I think it would probably be difficult to find your way from the airport if it was dark. Someone else might be able to comment if a taxi would take you. In some cities, they wait a long time for an airport fare, so object to short rides.
This apartment worked well for us. Rather than deal with the unpredictable time to get a taxi, and negotiate the traffic to the airport, we knew exactly how long it would take, so managed a good bit more sleep and uncertainty before a log day with flights to Europe. I recommend if the logistics work for you. I am attaching a pic, which shows the airport terminal from the apartment window. It is close. As you can see there is construction nearby so the details could change, and more recent reviews could be more useful.
