Mario & Melvin were very welcoming and helpful. The flat was correct, although it was less "authentic" than expected (posters everywhere on the walls warning the guests about the use of appliances, etc., Amex logos on the night tables, etc.). However, the flat was neat and convenient, very very well located, there were some water and beverages offered and the hosts' team helped us very kindly with our arrival and with storing our luggage for the checkout day.
