My question is about the use of present perfect tense. To my knowledge this tense is used for the actions that have started in the past and continues up until now. I have questions about different cases for the same thing:
1)Lets assume that I went to another country for a vacation and I stayed there for a few days. Now today is my last day in that country and now I will return and I am calling a taxi and the receptionist in the hotel asks me how my trip was and I answer him: It's been lovely to be here or to stay here /It was lovely to be here or to stay here
2) I am in the airplane waiting to go back. Now another persons asks me the same question and which tense should I use?
3) I have returned and I arrived at my home country. for example my father asks me the same question and which tense should I use?
Thank you very much for your help.
