This apartment was clean, comfortable, roomy, and well-equipped. Our four kids (16-10 years old) all enjoyed having enough room, a full kitchen where they cooked their own allergy-safe food, washed delicious fresh fruit, and fried plantains for the first time. Wifi was reliable in the master bedroom. The air conditioning had a slight fault, but the manager, Annett was friendly & efficient; she had a worker out to fix it immediately. The building has an elevator, and narrow stairs for the impatient and energetic. Street parking is very tight, but when we arrived Wanda met us with the keys, had saved us a space, and persuaded a local policeman to let us park in front long enough to unload our luggage; we would recommend using the public lot at the foot of the hill as the most economical option.
The apartment is in a great location in the heart of old San Juan, within steps of a 500 year old cathedral, shops, restaurants, even a beautiful little museum dedicated to Felisa Rincon, first woman elected mayor of San Juan whose social programs inspired Head Start in the US. The National Park sites are all within walking distance and have so much history; Puerto Rico was the first place to water after an Atlantic crossing. A small supermarket is just a few blocks away, and we passed so many enticing restaurants.
We used a rental van to take day trips out to the rain forest at El Yunque National Forest, a beautiful place to hike and enjoy the local flora and fauna. Food service there was rudimentary, but adequate. The humidity and warm rain were so different from California; I wished we had more time to hike the trails. We also made a day trip out to see the radio telescope at the Arecibo Observatory, where the world's largest single-aperature telescope was built in the 1950's. It is still an important research tool today. Our kids were amazed and impressed. There is a very good museum there; you can spend hours at the many displays.
We didn't use the balcony as much as I had expected, mostly because the heat inclined us to turn on the air conditioning instead. For early risers and those who visit during cooler times, the balcony is a great place to observe the quaint cobbled streets and church forecourt. Close enough to everything but far enough to be quiet for restful nights. I would highly recommend this apartment as a base to explore all of Puerto Rico, whether for a long weekend, a week or two, or longer!
