I had a great stay in Enrique's flat. It is light and open because of the two floors - and the balcony is big and nice. The kitchen is small and simple, but it has what you need. I was working from the flat, and internet was good.
For me the neighbourhood is perfect - close to public transportation (underground, commuter trains and many buses), but also to bars and restaurants. You are not living exactly in the restaurant area - you have to walk for some minutes. But is is a nice area for walking.
I really appreciate that the flat is close to the beautiful Palermo parks - perfect for jogging and walking.
Both Enrique and his son (who checked me out) are great hosts, helpful and willing to give you a lot of good tips and advices. And both of them speak English really well.
