I stayed in Patricías flat for 4 weeks during November- December. I absolutely loved the flat, it is very central and you can walk basically everywhere within the city center from there. The tram passes by just outside the door, as does the airport bus. Patricía was a very helpful host and always answered emails and texts very quickly. I have no complaints at all. I highly recommend staying in this flat- it is a perfect place to discover Lisbon from.
