Location: less than 25 minutes from the airport, less than 10 minutes walking distance from train station. there is NO uber. Only local taxi. You might have a hard time to call taxi if you phone does not have an international plan. Train starts operating at 6 am.
Place: neighborhood seemed nice and safe.
Wi-fi: it was ok. I guess it is not ideal if you want to work homeoffice.
I recommend to do the bus tour ($18) to see around :)
