We stayed 2 nights at the place. It's very close to the sea (10 minutes walk), great bakery (maybe 5 minutes), etc. Parking on the street might be difficult, but we were quite lucky to find a spot quickly. Right now the street parking is free (maybe its just paid in the high season).
Unfortunately the sofa-bed is really uncomfortable. Usually I can sleep in any conditions, but here I couldn't sleep at all. The mattress is not flat, it sinks in the middle, and you feel like you're rolling down all the time. I see another review mentioning that, but it was not fixed. Well, at least it forces you to wake up earlier and have a walk by the sea :-D
The flat is quite small, but has everything you need (kitchen is well equipped). It's a bit too dark in the evening in my opinion (it's missing another light source; we just used our candles ;-).
The balcony is definitely a plus.
The check-in/check-out was nice and easy. The communication was great and we booked it last-minute just a day before.
In general, I would be very happy co come back when the bed is fixed :-D However, sleeping well is the priority, so: 3/5.
