We stayed in this apartment for the New Year's weekend and it was lovely. Highly recommend using the transfer service upon arrival from airport so you don't have to figure out where it is and someone then meets the driver to let you in. This was all seamless.
There are lovely shops, restaurants, parks and bars very close by. All are reasonably priced and high quality.
The space is great, just what we needed for two adult sons and me and my husband. The unit is a 3rd floor walkup- (4th floor if you're from the US!) but clean hallways and quite secure. Kitchen was well equipped and the upper level primary suite was private from the rest of the space which was nice. The verandas (3) are all very nice. We cooked in the kitchen once for dinner and had all we needed in terms of equipment. No problems whatsoever, everyone on the team was lovely. We miss Lisboa already!
