I like that it is easy enough for people who are not travel professionals (like me) or those with little time, but still want good service in an area they don't know well yet! The cost of services can be high depending upon where you stay - however if there's no other option available then this may work out perfectly fine as long your hotel has wifi access so all rooms/lodging have free WIFI.
If staying at hotels without WiFi make sure someone else doesn’t use their internet before yours!! Otherwise just remember what we read above about paying too much :). Great app when used correctly-it will help eliminate many problems associated wth being newbies around foreign cities & countries such as food options / restaurants etc., transportation issues once arriving into town from airport; general safety concerns while traveling alone which makes using apps very useful especially during nights hours after dark.
