Great apartment in a very central location within walking distance of most tourist attractions. The apartment was spotlessly clean and there is plenty of space.
My only qualm would be that the host describes it as "luxury" and, while the apartment is well presented with nice decor, the stay was missing some little touches to truly be considered luxury - for example the hosts provide a dishwasher but no tablets, a coffee machine but no coffee... these are things I wouldn't mind buying myself if I were staying for a week or more, but I suspect most guests will only stay a few nights and so these types of things ought to be included in my opinion for it to be considered "luxury".
All things considered though it's still great value for money and I'd happily stay again.
