Tacky lobby
Marriot is for me, my home away from home...
This hotel is well located, you have theaters, restaurants, metro station, bus station very close.
The street is not nice, but doesn't feel insecure. 
Room & shower are ok. Free Internet was niiiice.
Three things had lowered the rating: 
1- can't stand the lobby, with loud music, noisy huge guards (from the nightclub that shares the hotel lobby), and the constant line outside the hotel... I felt like entering a tacky nightclub, every time I arrived to my hotel...
2- although breakfast is free, it starts at 6 and ends at 9!! Who can make it?????... And the breakfast place doesnt invite to have any food there... Is just a place packed with tables and chairs...
3: air conditioning is noisy, so every time it turns on, wakes you up.
