What can I say! The super host status is well deserved here. Communication was excellent throughout the whole process and everything went very smoothly. The apartment was exactly as in the pictures and we didn't want for anything. I can happily recommend the apartment and the hosts. I wish my own house was finished to such a high standard. :)
A few tips for travelers. We got the red line and the green line in from the airport. It was very easy to navigate and only €1.50 per person. When you get off at the nearest train station it is only a 10 minute walk to the apartment.
For a good local supermarket, come out of the apartment and turn left. Walk down just past the church on your right hand side of the road and on your left just past the CEX store is a good supermarket that has all you might need. A nice tip is they have a bakery in store and you can get lovely freshly baked pastries in the morning.
There are lots of nice places to eat but one we found very close by that is definitely worth a mention is Restaurante Sucolento. It's only a couple of minutes walk from the apartment. Try the pot of pork for two. It's delicious and very reasonably priced. The owner is very friendly and very passionate about his food.
The aquarium was a lovely half day trip and the bus that took us there (from the train station) also took us out to Belem for the afternoon. We also did a Sandemans free walking tour which was great and it gives good ideas of other things to do and see.
All in all we had a really lovely trip to Lisbon and would highly recommend it. :)
