Omid is a very nice host and gave us a totally warm welcome, even though we were 2 hours late because of a delayed flight. His apartment is close to Alfama, a nice old disctrict of Lisbon, but also the rest of the city can easily by reached by walking. It is lovely furnished (e.g. huge blankets for 2 persons in every bed :-)) and was totally clean. However, the aparment is also very clairaudient: you will hear everything from your roommates and the rest of the house, so better bring earplugs :-)
