The good:(1)FANTASTIC view and perfect location in Thira. 10mins walk along the walkway to the center but still off the main pathway so less people-traffic passes in front of your terrace compared to other places. (2) interior of the apartment is really cozy and comfortable with a basic kitchenette to make simple meals. (3) nice sized washroom and the hot water warms up quickly for your shower! (4) there is free wifi which is great! (5) easy bus connection and easy to find (6) Elvira is super friendly!
The bad: (1) you share the terrace with 3 different rooms; in our case we arrived with 3 people smoking and drinking (and we are not smokers), and with the wind our cocoon smelt of smoke when we arrived. Empty bottles and glasses were left on the tables for more than a day which was a bit unfortunate, but our host cleaned it as soon as she saw it. (2) not all kitchen dishes were clean when we arrived so we had to rewash them when we used them, and the butter knives cut tomatoes better than the 'sharp' knives... (3) soundproofing between cocoon and the other apartment isn't good so you can hear the voices of your neighbour quite well. (4) nothing to sit on inside except the bed, so if weather is bad (was for us), and you can't eat on the terrace, then you are a bit stuck.
Bottom line: nice place in a good location that is easy to get to with the basic essentials to use as a base to visit the island.
