Location of this apartment is great. Walking distance to many of the main sights and close to lots of markets/restaurants.
The access to the unit is down several steps and through the mechanical room. This entrance to the unit smelled of sewage as all of the pipes for the building ran through the mechanical room used to enter the apartment. This was a huge turn off, as my wife would wait outside in hall as I opened door and then run through holding her breath as the smell (especially) in the morning was awful.
The outdoor patio was small but workable. Unfortunately it too had a strong odor to go along with construction in the adjacent unit. Because the construction was directly above this unit, debris and dust would cover the table and chairs outside, making this space unusable during our visit. This also lead to some hot nights as the odor and dust meant we had the windows closed w/o AC.
The rest of the unit was fine. Nothing special but did the job. I'd give this place a 2.5 / 5
