Alejandra's place is great - it's a condo building right on the beach, so the views are beautiful every sunrise, and if you do want to take an afternoon break, you can be ankle-deep in the waves within 5 minutes! I spent many mornings just sitting on the balcony and watching the sky change colors.
We stayed here about a month, working remotely, and we had no problems with the internet (the router is in the unit, so we were also able to plug in via ethernet). There are three TVs, one in each bedroom and the living room, so there were plenty of screens if we didn't agree on what to watch. The kitchen also had plenty of dishes and basic cookware (a small sheet pan for roasting/baking, various pots/pans for stovetop cooking, etc.) as well as basic pantry items (seasonings, oil, sauces). The place also has beach chairs, plenty of towels, beach toys, and a boogie board.
We didn't have a ton of requests for Alejandra, but the few times that we did (asking for the WiFi password, initial check-in), she responded promptly and helpfully.
We found the unit very clean. Parking (valet) was $10/day, very reasonable for the area/setting, and there was also a gym on the ground floor that we occasionally used. Walmart was just over the intercostal so most days we'd just take a 10 minute walk there and come back with groceries and snacks. It's also a couple minutes walk from a restaurant called Etaru, which we frequented, and a nice 2 mile jog from the Hollywood Beach Broadwalk. Overall, it was a really good stay, would definitely stay again if we were in the area.
