Almost everything was perfect. The location couldn't be better and so is the amazing view the apartment offers. The flat offers everything you expect from a highly rated apartment on airbnb. Communication with the Maria was fast and nice. She had good recommendations for us.
The only thing that bothered us was the sometimes very slow wifi connection and the subpar heating system, which could be a problem in winter.
If I ever visit Lisbon I would choose the same flat for my stay.
