From all airbnb experineces this one unfortunately I have to value very low in terms of service offered. Word "luxurious" in the description has nothing to do with the reality of apartment offered. Value for money for me totally can't coincide with proposed quality. I would descride my experinec as I paid for 5 star hotel and was putted in 2 ones. For example facilities are old and amortised, part of electricity plugins dont work, kitchenware are old and some can't be used cause they are broken, in bathroom no doors, only curtains, etc. All this from my point of view can't be considered as luxury level as it proposed by the host. Apart I had unpleasand 2 days conversation, loosing lots of time to cancel reservation and due to bad communication with host's representative was informed incorrectly about the procedure and it putted me in situation where I had to dedicate time for solving it with a chance to pay and get nothing in return. Luckily was resolved but nevertheless cost lots of effords and energy and still feel like paid too much for the service in general.
I live in Barcelona and know very well the city, I saw and rented many short-term apartments for my work needs and believe my reference if fair enough in its valuation as I can compare offers on the market.
