We had a very pleasant stay in Finca Vistas Salinas in November 2016. Temperature was good and lots of sun. The apartment are well-equipped and spaceous. Quite a lot of privacy in the apartment "Femes". Nice swimming pool and relaxing chairs under the palm trees. Can be quite windy in November.
The Island is good for surfing/cycling/hiking etc. We loved it!
The apartment is not totally water-proof; after a night of rain some water entered into the apartment. The maid cleaned this neatly.
Furthermore, we had bad luck with the electricity switching off twice due to overload.
Recommendation for the swimming pool: the water of the pool and jacuzzi needs to be heated more to support the relaxed feeling (in fact, the water was quite cold).
