I visited the flat with 5 of my friends and we all loved both the flat and Carmela.
She is very sweet and waited for us (with a basket full of fruits) in the flat, even after our flight was delayed and we arrived at 00:30. She is also knowledgeable of the city and provided us with very useful suggestions.
The flat is very cosy and matches the description perfectly. It is well equipped, clean, and well maintained. It is within a 10 minute walk to the metro station.
The neighbourhood is nice and quiet. No problems with anything.
