As long as you are okay to walk up hills and narrow stairways (part of the Lisbon experience!) than I highly recommend staying at Ulrik's place. He was very responsive when communicating and provided many local tips and recommendations. The place was as shown in photos, although it would be quite small for more than 2 people. I was traveling by myself so it was perfect. The location cannot be beat if you are interested in staying in the Alfama area - just bring your walking shoes!
