Perfect place to explore Lisbon, and with plenty of space for a large group. We were 8 people and the space worked great for us. Check-in and check-out went with no issues and Joao was very accommodating with our check-in time. He also arranged for a transfer for the airport on our departure. Communication with Joao was also with no issues. He always replied promptly and throughly.
To be aware: The kitchen is small compared with the rest of the place and there were not many kitchenware if you plan to cook a lot. But then again who would worry about cooking with many restaurants and great food all around? Also be aware that there is no elevator, only stairs. Keep that in mind if accessibility is a factor on your stay.
All things considered we loved the place and would definitely stay here again. Thanks, Joao!
