This hotel/residence is connected to a mall, yes. To get to this mall, one can cross the go out by the concierge/check-in area and walk across an indoor parking lot. This takes one directly to the mall. There is a hypermarket there as well. If one needs to use a metro, there is a metro line that runs adjacent to the mall. After having used it several times during the stay, it is about a 20 minute walk from the hotel itself (cross the indoor parking lot, into the mall, follow the signs).
As for the hotel, all of the staff were friendly. The hotel is clean. One needs to be aware that these are the Pullman apartments. There is a Pullman hotel attached to these "residences" and getting to that is a little tricky. One must go upstairs to the pool deck and into the sauna area. One must use two different elevators in order to access the "Pullman Hotel". There may be another way to access it, however these were the directions given. The "Pullman Hotel" section of this complex is where the sports bar and Restaurants are located.
Room service was ordered several times during the stay and arrived in good time with no issues each time. The "residences" will deliver groceries from the mall-hypermarket to your room for a fee. Otherwise it is convenient that the hypermarket/mall is in relatively close proximity to the residences.
Hopefully this post will be helpful to others whom wish to book here.
