Ivan's flat is a fabulous spot to stay in Lisbon and it is perfect for two couples. It is easy to get to via the metro, though you do get in shape walking up some steep hills - welcome to Lisbon. It has easy access to many of the great areas, e.g. Alfama and Barrio-Alto and there are excellent restaurants within easy walking distance. I highly recommend Ivan's flat and this location for a visit to Lisbon.
