5 stars: I really love the whole conecpt of the app! Using the phone for everything is a bliss. The no contact check-in and out and the key is easy to handle. Maybe the only thing that has bothered me is that when I used it for the second time (my partner always added me as a second guest, so I wasn't the main user) I had to put in all my info again. It bothered me a bit but I had no huge problems with the app.
5 stars: Nice Person in a front desk .everytime I'll send a messages .they can reply immediately.And they can update me always.
4 stars: my stay at spa was great using AeroGust was good will use them again
3 stars: Door key doesn't work
2 stars: Let's see, it is easier to go to the reception and grab the key than use the digital check in, I tried many time to grab my booking with the app I only get the message try later, then I do the check in, using the website they sent me, I am checked in but the key doesn't appear in the app, I used twice, so far it is not working for me
2 stars: Doesn't use your info from reservation. you have to enter everything a second time.
