We have never met Ingrid in person because she is not living in the appartment, so we only texted. The family that actuallly lives here is really nice and kind.
Untill we came up to the door we hadnt gotten phone number to call for someone to let us in. We arrived around 1 am (which we paid 20€ extra for) and Ingrid was very upset about the fact that we 'woke her up' and rude via WhatsApp. Saying things like 'this is not a hotel but shared apartment' is not the best first impression a person can make, especially when you paying extra for checking in during night - It might not be the hotel, but its not a charity as well.
Eventually, our stay with the family was good, however,the way Ingrid acted made us feel unwelcomed and we wouldnt recommend staying in this apartment to anyone who whishes for a problem free check in.
