I couldn't recommend Pedro's place highly enough. I stayed for a month in Pedros and didn't want to leave. His apartment has everything you could want. It is very central (5 mins walk to barrio alto) and the neighbourhood is very authentic with lots of charm. The views of the Tagus are fantastic and the pictures don't do the view justice. The coffee machine was essential along with the wide array of tv channels when staying for the month. The house is very nicely decorated and somewhere that you will find it easy to relax. Pedro was also an excellent host. He ensured we had no issues and wanted for nothing throughout our stay.
