The apartment is as described. It is very clean and well kept. The location is great for me. It is a few blocks to the beach, but it is a straight shot and should not present any problems for most people. If you are familiar with Copa, the apartment is located after Rua Tonelerno as you walk from the beach. The apartment is spacious, but I would probably limit it to 4 people. However, depending on the situation it can fit 6. The sofa that converts to a bed in the living room is a bit small, so there is not a lot of "comfortable" sitting space in the living room. That said, I think the balcony more than makes up for anything. It has a great view and provides an excellent space to just relax and take in the surroundings.
Laura was a great host. Though I did not get to meet her in person, she was extremely responsive to messages and provided a smooth hassle free check in and out process.
I definitely recommend this apartment for a stay in Copa. I look forward to returning and staying in Laura's apartment.
