I'm from Singapore.
Alicia and her friends are a nice people. Unfortunately I didn't meet them, but I would host them again.
What a lovely young couple, very easygoing and my wife had a great time chatting with them about Singapore. Please do not hesitate to host them as they will look after your apartment and be as delightful as any guests can be. Highly recommended!
It was a real pleasure to meet and host Alicia. Very nice couple - I can certainly recommend hosting.
They are welcome back any time.
