We stayed at Matthew's place for over a month, while working remotely from there. Matthew was kind enough to provide both me and my girlfriend with desk chairs and a desk, which really made the difference. Internet connection was also very stable. The apartment doesn't get too much direct sunlight, so if you're planning on working from there know that you may need to turn the lights on at times.
Apartment is fully equipped to cook and having a dishwasher is simply amazing for long stays. The apartment is starting to show its age here and there, but no dealbreakers. Place was very clean, equipped with beach gear and toiletries and even though the laundry is shared with other units, we were able to use it every time we needed.
Location is amazing, nice and quiet neighbourhood while very close to US-1 and plenty of stores, it couldn't be better. Also, ducks (with ducklings!) come and go around the area and they even visit the apartment's front yard from time to time, which we found hilarious and relaxing while working.
Overall, we'd definitely recommend this place to someone who wants to work remotely and visit Fort Lauderdale.
