I enjoyed having a spacious shower with proper drainage, extra towels and comfortable pillows (I think they were memory foam ones).
It was great to have an electronic means of access. This is like having hotel access cards - each guest is independent and doesn’t have to return to the apartment together or carry a second set of bulky keys.
It was super easy to communicate with Barbara, she would respond almost instantly, which is great. Her detailed apartment guide came in handy as well, we used the taxi listed there to get to the airport, which arrived in 4 minutes!
