Joao's home is not only beautiful and modern, it's huge! You could easily fit 10 people comfortably as long as they're okay sharing a couple of rooms. The living room is easily the best feature by being so open with big natural windows. I'm confident you won't find a space like that.
There's also an upstairs patio space which faces all the top sights in the city. The view at sunset is breathtaking and we went up there every night.
The place is located on arguably the nicest street in Lisbon. It's quiet enough for when you need it to be but only a few Euro Uber away from anywhere you want to go. We thought it was the perfect retreat to return to after a big day.
I would highly recommend you book this place if you have a large party who want to have a great experience in the city.
