We had a very friendly welcome from Gonzalo, who met us at the nearby Metro station when we arrived to escort us to the apartment, a 5 minute walk away. He is a lovely friendly guy and was only too happy to give us recommendations for places to eat and visit. Gonzalo sent us text messages during our 5 day stay to make sure everything was OK, as well as texting prior to our arrival to confirm arrangements for getting to the apartment.
The apartment was well located in the Alfama district - an area we specifically chose in order to be in the old part of the city. It's an easy walk into the heart of the district and the numerous fado bars and restaurants. There is a really interesting flea market twice a week (Tuesday and Saturday mornings) a stone's throw away from the apartment.
The apartment was as shown in the photos and it was lovely to have terraces at both the front and back, with views of the river from the front. It is an old building and there are some quirks, as you'd expect in any old building (eg the shower is a little cramped, but really not a problem); it is also up on the 3rd floor and there is no lift in the building so you need to be reasonably fit to get up and downstairs. Again, not a problem for us as a reasonably fit couple in our late 50s/early 60s.
We enjoyed Gonzalo's CD collection, especially some of the jazz that he has on disc.
All in all, a comfortable and very pleasant stay - our first trip to Lisbon.
