Mónica is a fantastic host and the location is perfect.
As soon as I landed in Lisbon, she was communicating with me and was patient with me even though my phone didn't seem to be working and it was about to die. I simply said I was on my way to the apt (without knowing any real timeframe) and then my phone shut off. I just had to hope she would be there when I finally arrived and after wandering in the streets for half an hour after the taxi let me out at the wrong location, I found the apt and there was Mónica, patiently waiting for me!
And it gets better. My friend had somehow left his wallet in the aforementioned taxi and he was panicking and thinking his trip was essentially over, but Mónica and her friend spent the next 10 minutes talking on the phone to different people at the taxi company until they were able to track down our driver. Then they walked with us to meet the driver and waited with us as that taxi driver drove across town to meet us. During this whole time, Mónica never once looked impatient or annoyed with me, which I really appreciated since the situation was out of my control. We got the wallet back and the crisis was averted thanks to Mónica and her friend!
The apt was great too. I really enjoyed the residential feel of the area and felt like a local among tourists. Next time I'm in Lisbon, I hope to stay here again.
