Maria's place was big, clean and easy to find. The check-in and check-out process was flawless, communication as well! The only downside is that it was darker inside than I was expecting it from the pictures.
The washing machine was a nice extra to have.
At this period, the neighbourhood was relatively quiet (no problem to sleep in the bedroom in the back) and my relatives had no problems going out, despite the area seeming a bit sketchy if you're not used to it. Being able to choose from 2 metro lines was great (around 10 minutes of slow walk for each)!
Maria also gave a useful and complete guide about where to hang out and eat, my relatives appreciated it. Thanks Maria, on their behalf!
