The apartment is very centrally-located on Rue St. Honore. It is a great option if you wish to be close to all the tourist attractions and the shopping area of Rue St. Honore. The apartment is beautiful, clean, and has many modern and high-end amenities. It also has air-conditioning and is serviced everyday, which is not common of AirBnB apartments in Paris (we found).
If you need to check-in early, HighStay also has a place a few doors down where they can store your luggage. However, there is no place to sit or wait until you can check-in. We arrived on a very early flight (before 6am), and with the rain, it was difficult for us to find a place to go to, to shelter from the rain and also get something to eat. Many of the restaurants in the area do not open until 8am. Perhaps there were some on Rue de Rivoli which is just a few blocks away.
Communication with HighStay was easy and they were very responsive. When we go back to Paris, we would definitely consider staying at this apartment or another one of the HighStay apartments again.
