The apartment is located in the, in my opinion, most beautiful part of Lisbon called Alfama. We enjoyed our breakfast every morning on the balcony with sea view, it was pure bliss. Keep in mind that it's the loft apartment though, so you need to climb 4 stairs before you get there.
Also, the apartement is very well equipped (washing machine, dishwasher, hair dryer, flat iron, microwave, kettle) I really recommend staying at the river loft!
