Cosy little apartment in a very convenient location. With a 24hr corner store just on the corner, we were never without staples or snacks. Short walk to Martim Moniz (start of tram 28 line) and Rossio squares (train station goes direct to Sintra) and also walkable to the riverside and all its sights. Taxis are also easy to get from the front of Hotel Mundial (in Martim Moniz). Plenty of restaurants nearby and Nuno is great with his recommendations of local eateries (although if you want to get a place at Ramiro's I recommend either getting their VERY early or bringing your patience - we gave up and went to another seafood place down the street).
Unfortunately we found that with 4 adults and luggage (Lisbon was part of a greater euro-trip), the space was quite cramped. There is only one bedroom and a sofa bed which requires the coffee table to be moved to a corner when it is folded out. The hot water system also can't cope with 4 consecutive showers, but doesn't take too long to heat up again.
Overall, we had a great time in Lisbon. Thanks again Nuno!
