Pros: 3 tennis courts (2 hard, 1 clay) and hitting walls (!), quiet location, pool, poolside wifi, sauna, outdoor hot tub, condo beach and chairs included, very close to Smathers Beach. Indoor parking, elevators, luggage carts. Large clean suite, well-equipped kitchen, tile floors, wide balcony, 3 TVs with cable, A/C, washer/dryer, 2 beach chairs, 1 beach umbrella, pool noodles, wifi included.
Cons: A lot of pool restrictions. Non-swimmable condo beach. Location somewhat of a distance to Old Town. Landline phone didn't work, food processor didn't work unless you MacGyvered it, toaster slots too small for regular slices. Master toilet had some flushing issues.
Problems listed above were very minor compared to the benefits. Quiet place, mostly older people but we liked it that way. Pool restrictions not a problem as the swimmable and the public beach is walking distance away. We rented bikes to get around.
Tennis courts are under a reservation system. However people usually don't play tennis much after about 10 am so one could always get a court by then without having to reserve.
Overall an excellent stay. Not cheap, but you get a lot for the price and it's comparable to similar places nearby. If you want a quiet stay in Key West where you can play or work on your tennis, this is the place!
