We very much enjoyed our stay at Limehome and would likely consider it again. The location was perfect. Short walk from Dusseldorf Central Station and short walks to the canal, central shopping area and the Rhine River. Should you drive or hire a car, there's parking opposite (though €30 euros for 24h). Nearby is a lolvey cafe called Velvet. The apartment room was beautiful and clean too.
The negatives; we mistakenly booked for 4 rather than 3 days. Even though we notified them within 30min of this mistake they wouldn't refund us the amount in part or in full. Our room faced the front and was easily peered in from the office building across the road. The kitchenettes in the rooms are very small and you will feel cramped if staying for longer than 3 or so days. There is a lack of communal facilities or vending machines for spur of the moment snacks etc. Lastly, their didn't appear to be any permanent on-site staff, so if you did have a problem or enquiry such as noise, leak, wanting to book a taxi or find out more about the area and things to do, I would imagine it would be tricky to have these quickly resolved etc
