Sylvia is real good. She gave us lots of useful information about Lisbon. She is very helpful. I suggest you take her service on airport pickup and drop off. I also recommend WhatsApp for easy communication with her. Everything is good in our stay in the place. The only thing that is not excellent is the toilet, other people's review already mentioned that...it is true. The toilet is in the closet with no ventilation. Other than that, everything is good.
