This is a good place to stay in Santorini. Elvira was very welcoming, friendly and quick to respond to any communications. The views are great and it's in a good location. However, there are a few downsides you should be aware of.

Pros:
+ Welcoming and friendly host who communicated with us very quickly
+ Informative check-in, pointing out places to go, local history
+ Help arranging transfers and a porter
+ The best bed of any Airbnb place I've been to
+ Powerful shower
+ The best shared/public wifi we've used in the Greek Islands (but still slow at times like everywhere else)
+ Great view of the caldera
+ Located centrally, but not too close to the very touristy Fira/Thira
+ Kitchenette is well stocked and came with water, wine and juice
+ Torch on the keyring and books in the room were thoughtful touches
+ Luggage storage was useful
+ Good value (for Santorini, that is)

Cons:
- Lots of steps to and from the apartment, so difficult with heavy luggage. Elvira arranged a porter for us for the return journey, but it would have been nice to have this suggested for the arrival - another Airbnb place on the island arranged this for all guests.
- The shower is powerful, but a lot of water ends up on the bathroom floor.
- No air con. A fan is provided, but we had trouble sleeping.

Elvira was an excellent host - one of the best I've encountered on Airbnb - and if you stay here, I'm sure you'll enjoy it. However, make sure you study the other Airbnb places around: we stayed in another that was more expensive, but had air con and an even better view.
