Huge apartment with everything one can need. Good quality appliances, regular WiFi, good AC and nice floors. I will instal some blinds for the main room, but there's no much light anyway.
Some local person told us the neighbourhood isn't the safest, and effectively at night you can 'feel some heat', but the subway are a couple of blocks away and the train station is really near, so it isn't bad. It is also far from the party neighbourhood, so less touristic and calmer. There is a big square around the corner with several restaurants and more than one bakery. There is also a mini market at the corner that closes up to eleven.
In some circumstances, I'll prefer to have an autonomous arrival, especially not to be extra charged for arriving late, but other than that, it's OK to talk to someone when entering the flat for the first time.
The only issue we had was a leak on the shower, but I'm sure they will fix it.
