Apartment is in an easy, central location close to a metro stop. As others have mentioned, Tiago leaves a list of personal recommendations which was a nice touch.
Things to be aware of: the apartment is directly above three bars, making it loud at night. This was not a problem for us, but could be for others. It was also on the fourth floor and the stairway is steep.
We had a few issues while we were there. The air conditioner did not work and while Tiago offered to send a repair person to fix it, it would have meant us waiting around which was not a great option. The shower didn't drain properly, but at that point we didn't bother reporting it since we didnt want our stay to be disrupted.
Overall it was an okay experience and is a good option for a cheaper place to stay, but the apartment could use some maintenance in between guests.
