It's understandable, but not completely correct. It would be good to say it differently. For example: During my stays in X, I came to the conclusion that each of the hotels A, B and C have ocean frontage and are all very good. The nicest part of hotel A is that it is right next to the XX, where it's very convenient to access my favorite coffee shop from. I hope I didn't misunderstand something :) good job, anyway!

It's a bit difficult to put "ever" neatly into a positive sentence. How about these suggestions? "From all the times I have stayed in X..." "From my experience of hotels in X..." "From having stayed in X on several occasions..." "...A, B and C hotels each have more ocean frontage and all are very great." (More ocean frontage than what?) ("Very great" can mean physical size. Perhaps "simply wonderful to stay in" might be closer to what you mean.) "The nicest part of A hotel is that it is right next to the XX where there is very convenient access to my favorite coffee shop." "The nicest thing about A hotel is that it is right next to the XX where I can get to my favorite coffee shop easily." (You could replace "easily" with "without hassle", or even "without becoming roadkill" / "without becoming a statistic" if you want to humourously suggest the local traffic is very busy.) I hope this helps!
