We had a great stay at William and Anthony's place, such an amazing location, walking distance to almost everything that we wanted to do and only a 5 minute walk to a metro station. The place was perfect for two- keep in mind you do have to share a sofa bed but we didn't have any issues with comfort. The neighbours were quite noisy at night but this may have been due to the old style layout of the building. The hosts were so extremely helpful and accomodating in giving us tips and recommendations on where to go and what to see in Lisbon. We would definitely recommend that you stay here.
