We had a fantastic time in Elena's apartment. Very central, very clean and Elena was very welcoming! She gave us lots of tips re nice places to eat, what to see/visit in the city. The terrace is definitely a plus for evening drinks and nice breakfast in the sunshine. Elena texted us mid-stay to check that everything was ok/if we needed anything which was very nice.
I would recommend her flat, although the noise from the street might bother you if you are a light sleeper (didn't bother us apart from the 1st night). Overall a really great place.
