We enjoyed our stay in Nuno's cute apartment in Mouraria. The location is excellent, within walking distance of tons of great international restaurants and just a few minutes' walk from the Martim Moniz station. The space is small, but that's to be expected of apartments in the old city, and honestly that's part of the charm of staying in this neighborhood. For us, it was a perfect place to crash at night after a full day of exploring the sights of Lisbon.
