We stayed at this lovely little apartment for four days and it was a great base. It was spotlessly clean, stylish, comfortable and has everything you need, even a big umbrella, which for us was perfect as it was quite a rainy few days.
The neighbourhood is great. It's easy to walk into the more central and more touristy areas if that's what you want to do but is actually also well placed to spend time in other really interesting areas. I'd recommend booking a table at Cantinho Lusitano and a few minutes uphill at Rato, the local restaurant Rodas is great too. The area around Principe Real is well worth a wander, with great design shops and lovely bars. It's also just next to the stunning Miradouro Sao Pedro de Alcantara. And if you can, it's well worth the steep walk uphill to the lovely Jardim De Estrela. If you're into the arts, then the Collecion Berardo out in Belem is a must visit.
