We stayed as a group of 4 adults in what turned out to be an ideal, well equipped apartment as well as a perfect location for exploring the city. We were greeted by a bottle of local wine and local cheese, a perfect extra touch. Filipa & Sérgio also provide a free mobile phone with a number of local apps which would be ideal if you do not have an EU based one of your own. The area is historic, hilly with cobble stoned roads and pavements so probably not ideal if you have mobility issues as the flat is also on multiple levels down stairs. There can be a little noise outside the front bedroom especially at weekends but this was not enough to disturb us. There is a great selection of restaurants within a 5 minute walk we especially enjoyed le petite cafe just around the corner, there are also a couple of small grocery stores also within 5 minutes. The area itself is as stated on the historic tram route and can become very busy when the cruise ships are in port but we found a visit to the castle late afternoon (5 minute walk) found no queue for tickets or around the castle itself. If you are using your own transport arrangements rather than the owners be aware that the cheese and wine suites are at least a 30 minute walk from the apartments and our taxi dropped us at the wrong address. We would certainly use the apartment again should we be in Lisbon.
