The flat is nice and is ideal for a couple. It is in a great location - it's in the city centre, but not at all noisy. We had some issue with the shower hot water going off very frequently (every 3 minutes), but Sonia is aware of this so I'm sure it will be fixed. However, the apartment is very comfortable with a good bed, clean and a nice fully equipped kitchen.
We would definitely recommend staying at Sonia's place!
