My family of 5 spent about six weeks in Krystel's apartment and enjoyed it a lot. The apartment is newly and tastefully decorated and Krystel is a discreet but very helpful host. The backyard is relaxing with nice and comfortable patio chairs; there's also a fire pit, a grill and quite a few nice decorative plants as well as culinary herbs pots (basil, thyme, rosemary, mint). The place doesn't have TVs, which worked great for us. The internet connection is good and reliable and Krystel was kind enough to upgrade it right before our arrival when we told her that we work remotely. The unit has AC which was a great addition. There is a full kitchen stocked with utensils and pantry essentials and Krystel added a few nice touches to that, too. She welcomed us with local IPAs, sparkling water, organic milk and even a nice bottle of good quality "vinho verde" produced locally.
The neighborhood is safe and vibrant with lots of coffee shops, restaurants, grocery stores, quite a few small and big parks as well as excellent french bakeries.
It was a great experience for us and I encourage others to try it out.
