I have just spoken to her...did you just a favour

.
Definitely not Brazilian

, I started speaking Portuguese and she didn't get a word of what I was saying. She said she spoke Spanish instead, then I spoke Spanish with her, quickly, not a clue of what I was saying. I went back to English and then she said she spoke 6 languages

, well, I only speak 5 and can guarantee you that even her English is very shabby (give her a call if you want, you'll understand what I'm saying about her voice, also her voice sounded too raspy for a 23 yo, though I might be being biased by all the rest already).
I would say she is eastern European, perhaps Hungarian. From her English accent, don't think she is Romanian. Romanians are usually good foreign language speakers.
And she just texted me to book by text as she does not look at AW bookings. I would definitely stay away, not worth the risk. Just posting here to voice my suspicions. I would be an hypocrite if I didn't to anything.
