As an intern advisor at the UN, I made a reservation with Mariana to host a delegate of Palau, Joe Aitaro. From the start, Mariana was super about responding promptly and even called to check when the delegate took longer than expected to arrive after his flight arrived. Joe reported being happy with the place being close to the UN and in an interesting neighborhood. Mariana warned him it might be loud on the weekends, but his work kept him out late so it wasn't a problem.
