Stayed at the Alt in late January and it was a very good stay. This hotel has only been open for 7 months and it shows, its new, fresh, and modern. The hotel is very well located from Pearson airport with a convenient sky train from the airport to the hotel.
I booked a room via the Alt site and all my requests were honoured. I had a corner room fantastically located on the top floor(14th) and away from the elevator. The room was "L" shaped with a corner window with a clean modern feel and look. The rooms are sparse with amenities and are not well appointed. The rooms are very basic without a closet, iron,dresser, mini-bar, coffee machine, etc. This hotel is meant for short or overnight stay, but this should not take away from the quality of the stay. The beds are very comfortable and the washroom is smartly done with a walk-in shower and european wall mounted toilet. I'm not sure that the quality of the materials and the fit & finish will stand the test of time....
I highly recommend checking your bill before check-out for unforeseen errors. This is new hotel with young unexperimented staff and mistakes are bound to happen.
I enjoyed my stay at the ALT and would recommend it for a short or "fly in and out" stay.
