5 stars!
The terrass was very nice and useful in the evening (too hot during the day though). The neighbourhood so pretty.
The beds very comfortable (I have a bad back).
Clean flat and there was a cleaning service of the flat daily. There was also a laundry service for free (one time). Additional to that, the host was very helpful and his mother had left homemade cake for us one afternoon when we came back to the flat.
This is like a real home, very cosy.
Only thing to consider is that the flat might not be suitable for a family with very small children (1-2 years) cause there are rather steep stairs inside the flat. (Our children are 9&6).
Its also good to know that there are no doors inside the flat except to the bathrooms. So no bedroom doors. But that was not a prob for us.
