in.gracia is a small place on the ground floor/semi-basement of a nice building in Graça. It is located right next to the tram rails of the famous line no.28. Therefore, it might not be suitable for someone looking for a quiet place to rest during the day, but we were up and running since early morning and indeed got used to the morning trams :) The ceiling is a bit lower, but even a person 193cm tall can just about fit in the shower and the bathroom. The space is indeed big enough to make you feel comfortable. Ana is a great host and the place is, overall, highly recommended.
P.S. A great way to discover Lisboa is Gira public bycicle system. For 2 EUR we gained access to all of their stations around town. Some of the bycicles are electric and easy to ride even slightly up a hill.
