Everything has been as expected..and beyond !
Reyes and her friend Enrike really did make me feel at home, and provided all sorts of recommendations/help. Plus, they are very interesting people, whom I really enjoyed chatting with.
The apartment is very clean (Reyes is kinda hyperactive, and cleaning is one of her favorite "occupations"), nicely decorated, close to everything (either on foot or by bus), and has a great terrace.
All in all, I'll definitely get back to Reyes' place, next time I visit Palma.
