Highly recommend staying here. Cosy little room with own bathroom with easy access to the underground, even if it isn't right in the middle of central Lisbon, but it is by no means far out. There are a couple of shopping centres close by with all sorts of shops, supermarkets and restaurants, both conveniently located next to the two options of tube and/or train stations, that's it great links.
Really peaceful, you will sleep well, and Ana and Leonel are the most incredible hosts. Loved staying with them.
