I must say that overall I had a good experience booking my flights and hotels through BTCTrip.
Checked in for my flights to Ireland and Greece without any problem, with a piece of luggage included.
Also booked a hotel room in Paris for one night and everything went perfect, the room was already paid for when I came there so i had nothing to worry about.
Afterwards, I've booked a villa in Santorini, Greece for one week, had the best experience ever there.
I must say that I had to contact the support a couple of times after booking my stuff since there were some small misunderstandings but they fixed it quickly for me.
Keep the good work, guys!
