A really nice little apartment. I traveled alone but it would be also fine for two. It has all the basics you need and a really comfortable bed. It is private with that little patio (which is shared with one other apartment) and quite at night time. If you don’t mind a few stairs to reach it, it is a perfect spot to explore Lisbon, especially Alfama as it it is right in the middle of it.
And Isabel is a great host. Fast and helpful communication with her, which made my stay really easy. I can recommend this :)
