This was great. The best thing for sure is the location, a block from the beach and all the shops/restaurants. Yet it's very quiet inside, very good noise isolation.
The apartment is modern and the fact that some beach towels/chairs/toys are available is great, no need to lug those via the airport.
The main bed is good, others said it's firm, but myself I like that much better than a spongy mattress. The sofabeds are so-so, kinda small and ot very comfy, ok for the kids.
Lauderdale by the sea is nice, we went to Miami, Biscayne bay etc..., but the beach a block by the apartment was the best, clean water, refreshing, and good snorkeling. There are 2 reefs that are swimming distance (~ end of peer, there is a map sign on the beach), if you are a good swimmer with a flotation device. If not, you can rent a paddle-board or kayak for $25. Nice to be able to go snorkeling without needing a boat tour.
Ari lives upstairs so it's very convenient if anything is needed. It was also very nice that no keys are needed (all keypads), no keys to be exchanged or to worry about losing.
Would go again !
