The appartment is located in a building with 24 hours concierge. You do not get a key to the building, the concierge has to open the door for you all the time. They are always there, that's not a problem. The only problem I had is that on arrival, from a a 11 hours flight arriving around 10.30pm, the concierge did not know anything about our booking and would not let us in. Unfortunately we had to wait for about 10 minutes outside, my dad has hearth problem, so he cannot be standing for too long, but finally the owner called the concierge. The buiilding and the appartment are modern, neat and clean. The appartement located in the ground floor, so no stairs or elavatore is needed. Appartment is more spacious that I thought and the one and half toilet is very handy. Despite not having any window, the appartment has very good light system. All necesary appliances are included, there is also a washing machine. In the shower toilet there are 2 problems, 1/the door does not close, it gets stuck a few centimeters (aprox 5cm) before closing, this is something to be fixed, because the door open directly to the bedroom , so if you are not a couple, it might get weird. 2/the shower splashes everywhere because the curtian is too short(aprox 10cm above floor), there is a mop you can use, however after 2 persons showering, it's just too much humidity. I guess that's the reason why the door cannot close. If you are eco minded you might get annoyed that you have to let the shower run for a while after if gets warm. You do not hear noise from the street, but the isolation between apartments is not very good, you hear when people comes in an out, steps or voices. Nothing terrible, though. Other than that, we really enjoy our stay here. The location is a very trendy and it's a very happening area, popular amoung tourist, but very mexican too. Wifi works great. The sofa is a plus to sit and relax. There is also a desk in case you have to work. I will advice to add a lamp in the bed side table. And the remote controls either do not work properly or the battery is running out.
