The person who received us was very rude. He arrived 45 mins late, we had to wait in the street with all our luggage, he said to us it was our decision to wait in the street, not his fault that he was late, and that it was company policy to never apologise to clients so that the company wouldn't be liable for anything.
There were problems with the lights in the house, they sent an electrician 2 days later and he couldn't fix it. They didn't offer any compensation or alternative accommodation. The electrician left the place super dirty and the manager cleaned it himself badly instead of sending a cleaner.
The flat was very cold, the heating wasn't working and they had to come to set it properly, but even then quite cold and dark. Shampoo and soap provided was only for a few days and we were staying 7 nights. No basics for cooking like oil, salt, pepper, kitchen roll.
Internet was fast and the flat was close to amenities.
Not recommended overall, and definitely not luxury!
