Really nice and cozy place with a wonderful view from both balconies. It had everything we needed/wanted. And the balcony with the best view has sun the entire afternoon until sundown.
The place can be a bit tricky to heat on cold days (11ºC during the day and 4ºC at night), even though it is rather small. But if you only heat one or two rooms (don't try heating the kitchen) and you use the owners advice of leaving the heaters on during the day, it is possible. By the way even with only 11ºC outside, Lisbon is much warmer than you think on sunny days (and it is almost always sunny).
