I never had the chance to meet Mina in person, but she had someone there to assist me with the check-in and he was very kind to also help me to carry the luggage up the stairs too. The apartment is great and it's only mins from the U-bahn station and the laundry is just around the corner. Mina didn't contact me or provide me with the check-in details until I texted her again a couple days before my departure, she said her messages to me were stuck in the mailbox and didn't go out, it's a technical problem with the app, I assumed. so if you don't hear from her, better take the initiative to check for yourself. Other than that, everything was just great, the bed, the shower!! (best ever!)
