Great apartment in fantastic central location, just a few mins walk to some of the key tourist sites along with the waterfront and restaurants and bars. Also opposite both Rossio metro and 5 mins from Rossio overground station with a direct line to Sintra (highly recommend for a day trip or overnight stay). The apartment had everything we needed along with some helpful extras such as washing powder for the washing machine (surprisingly not always supplied elsewhere!). The train rumbles didn't bother us at all, we are medium-level sleepers and had no problems.
