The hosts (Aida and the owner Christian) are very nice and always willing to help (check-in 2am, late check-out, helped with the luggage, exchanging money, booking a taxi).
The flat was overall ok. It was disappointing that it is described as "luxury accommodation" and I found it all actually way too simple. The kitchen has very few appliances and of low quality and old, so you cannot really cook there. Furniture are only ok, not the best quality, old and some are missing or does not correspond to the ones in the pictures (for example, the rug was not the same as in the pictures, the armchair in the sleeping room were missing and the table in the sleeping room was not the same, but an ugly one).
On the other hand, it is very spacious, has good air conditioning (very important in summer) and internet was very fast. Location is also great.
All in all, it was ok, but not really good. It needed a good update to be worth the price.
