I recommend NOT TO USE this company! I have used this company several times because it offers cheap prices but I have decided not to call them anymore I prefer to pay a little bit more and have a safe, reliable and polite service. The three times I have used this company, the drivers have been rather rude and unfriendly (they openly asked for a tip after the service, on top of the fare). Three times of bad experiences is too much!
The only thing I can say is that finally they took me to the airport, but in a very unfriendly and unnecessary tense way. I don't want to see this company anymore!
