1. Hosts were very pleasant, professional, and on time with all meetings
2. Location might be less-than-ideal, depending on what you are doing: 2-3 KM from beach and from Ciudad de las Artes y Ciencas, and 3-4 KM from city center.
3. Public transportation is available but not as easy to understand as other cities, so taxis may be most efficient (reasonable rates but it adds up). With kids (we have 2), taxis were necessary.
4. This apartment was nicely furnished, however there were plumbing problems, and we had a very bad odor that made one bathroom unusable, and the kitchen barely usable for the duration of our stay (4 days 3 nights). Definitely check whether this has been sufficiently addressed.
