We loved our 6 night stay at Morgan Jupiter Apartments. The staff were extremely kind and helpful, letting us leave our luggage in their office before we checked in, giving us restaurant recommendations, giving us extra kitchen items that we needed for cooking, and transferring us to another room after a water leak sprung in our bathroom ceiling!
The entire apartment complex was recently renovated, is modern, and in a beautiful building. Our apartment was very comfortable, beautifully designed, with high ceilings that give it a spacious feeling, had a nice modern kitchen with a clothes washing machine and drying rack, microwave/oven, induction stovetop, beautiful furniture in the separate bedroom and living room, a comfortable bed/pillows/sheets, plenty of closet space, and a modern bathroom/shower.
The location in Lisbon City Center/business district, near the Marquis de Pombal monument, is very central, although there aren't a lot of cheap dining options nearby, so be prepared to go outside of the neighborhood if you want cheaper meals. This is a high rent, upscale neighborhood, with only pricey restaurants nearby. If you're on a budget, look to other neighborhoods for cheaper meals! One restaurant we liked that's only 4 blocks away is called Honest Greens. Delicious, organic ingredients, but not cheap.
Overall, one of the nicest apartments we've ever stayed in, with a superb, kind, and helpful team of staff that run the operation. Thank you Eduardo, Katerina, & Theresa!
