The location is great and the apartment it self is great once you are in. There is steep round stairs to haul your luggage to the apartment. As long as the bags are not too heavy or if you are fit person you can manage to bring the bags in the apartment. There is a picture in the listing showing the stairs entry from the apartment.
Also the only toilet there is very narrow which you can compare with an airplane size toilet and washbasin.
I am not trying to show above few things as negative but just FYi. Other then that the apartment is great and I would recommend.
Cleanliness I marked lower because we noticed a mice in the apartment once during our 3 night stay and never saw it again.
I never saw GMT and didn't need to but this shows that GMT is off site who needs to rely on his cleaning crew. I think GMT has done a great job to offer this apartment in great location and inside of the apartment is great but the cleaning crew has failed to hold up their part of the responsibility.
Location is so great that Metro station is just across the road, Taxies lined up right outside the apartment door. There is great view of the city from the apartment and I was able to hold my 6 large luggage in the bar next door after we checked out for few hours where we picked up the apartment keys.
