This was the cleanest and most spacious VRBO we've ever stayed at. The beds were very comfy, and so was the large couch (our son wakes up early to watch tv, so we put bedding on the couch, and he just slept there most nights). Both bathrooms were modern and clean, and the a/c units worked great - we never had them lower than 78-F. The kitchen was fully stocked with all we needed, including a coffee pot, and it was so peaceful having morning coffee on the private glass deck overlooking the water. The building is quiet & secure (24/7 security staff; key-required elevators), and we walked all over this part of town and never felt unsafe, even at night. Be aware that it's not walking distance to Casco Viejo/tourist areas, and the places that ARE walking distance (Super 99 grocery store, nice restaurants, Panamá Viejo, Parque Omar) have limited sidewalks, potholes, and litter. But it was a cheap ($6) Uber to most places.
Unfortunately, the day before we arrived, the pool was shut down for several weeks for repainting. Thankfully the host was great about resolving the issue. Also, the shower only puts out limited hot water, so you need to take quick showers and make sure no one's doing dishes at the same time. There's a washer/dryer in the unit, but the dryer is SUPER loud, so just don't run it at bedtime. And because this area isn't as touristy, it really helps if you speak Spanish (a couple of us did). All in all, we really enjoyed our 9-day stay!
