Vasco's place was great! He was very responsive to any questions I had. The place is within walking distance to Alfama and the Pantheon, although the walk back is a bit tough because it is uphill. There weren't a lot of super-close places to eat, but they were within a 10-15 min walk.
I enjoyed the sunlight streaming through the flat, the view, and how quiet it was. The patio is nice for drying your clothes and morning coffee. The bed was quite firm, but I prefer it that way. There are quite a few stairs but I didn't mind the workout. The kitchen has everything you need, and the induction stove is quite nice. I used the heater on cold nights but I didn't need to use the air conditioner at all. Overall I had a fantastic experience and would stay there again!
