This is a very clean, comfortable and well-maintained apartment. The only real negative is that the flat next door sometimes had their TV up very loud late at night, presumably to compete with the nightclub next door to them. The first night we stayed was really noisy and it ruined our sleep. The second and third nights were a bit noisy but tolerable and the last night was peaceful. Otherwise, everything was fine.
I only met Maria briefly when we arrived, but she was nice and check-in was hassle-free.
It's quite a long walk into the centre, but there are regular buses which stop nearby and get you there for 1.50 Euros.
The best thing about the apartment is the balcony, which gets plenty of sun and has a nice view overlooking a little marina.
