Great apartment in terms of its size but, OMG, how noisy! During the week, it was impossible to get to sleep before the on street concerts by the lift which generally went on until gone 1330am! Surprisingly, Saturday evening seemed to be the quietest evening!
Aside from the noise, having some form of window dressing would be useful so that you can let the sunlight in without being stared at!
For getting around, great central location and the transport in Lisbon was really good - clean, reliable and cheap.
Lovely apartment, an ideal size for two and Tiago was a very amenable host.
