Diana was very welcoming ! The check in went smoothly in the afternoon. We spent most of the days outside and only came back home to sleep at night or rest a bit between two outings so we didn't really get to see each other that often, but she was available whenever we needed something. She offered us beers, fruits, instant coffee, milk and all of the other necessities (towels, etc) which was a huge plus !
The flat was well situated : 5 mins walk from the metro and ~30 minutes of metro from most of the city's busy places. An elevator-based parking is available which was great as the immediate street parking is paid during the day (but free during the night), but there is a free one a couple of blocks away. The elevator parking suited us as we didn't use the car during our stay, except to go to far places where commuting takes an hour (whereas it is 15 minutes by car).
It was a great stay overall. Thanks Diana :)
