Pretty much everything is perfect about this place. It is a modern apartment overlooking the busy Martim Moniz square, close to all amenities and easily walkable into the city centre. If you fancy taking the popular 28 tram, you can see the queue for this from the apartment lounge.
Everything is set out to a high quality and was really clean and modern. Cristina is a great host and e-mails were answered promptly and clearly.
One thing to note (and certainly not a complaint or problem for us) is that the pedestrian entrance to the building is up 2 flights of steps outside the building. I understand that if you arrive by car and use the underground garage then there is a lift directly to the apartment, but if you're not driving you will need to be comfortable climbing steps. Just thought this might be worth mentioning.
We had a wonderful stay here, cannot recommend it highly enough and are already planning our next visit.
