Filipe and his girlfiend Lydia were very nice welcoming people who were happy to give advice on seeing the sights of Lisbon. One lunch time Filipe cooked me a typical Portuguese dish called "bacalhau" (salted cod) which I enjoyed. The apartment is pleasant, very clean and also quiet so a good nights sleep is possible. One guest bedroom, with bunk beds has a balcony looking out onto a small square. The other guest bedroom with a single bed has a partial view of the river and Europe's longest bridge. The apartment is a up a hill from the nearest Metro station and you do need to be fit to walk up to it. It was quite easy to get around Lisbon from the apartment. From there I also went by train to visit the towns of Sintra with its palaces and the seaside town of Cascais and then walked along the promenade to Estoril.
I had ten very enjoyable days staying at this apartment.
