Well written, YoYo. The only real criticism to be levelled is in the use of the term 'high-end' - fine as it stands but you used it five times, so better if you can vary the wording by using synonyms. I have suggested a couple but you could words such as 'elite', 'luxurious', 'high-class', 'exclusive',  'select', 'elegant', 'fashionable' etc...
