I spent two nights at the Serena on business. I liked it - pleasant rooms and bar and restaurant areas where it is possible to sit outside and enjoy the climate at any time of day. Lots of options for places to sit and have a drink or hold an informal business discussion. There is a pool in the gardens and it doesn't feel like you are right in the city - given that it is near the downtown area. About 20 minutes from the airport (if you arrive out of the rush hours). Food in the a la carte restaurant upstairs is good and the breakfast buffet and evening informal dining were also good standard. Wifi was efficient too. Staff friendly and efficient.
