Joao and joana are very nice, they were presents from the start to the end of ours holidays. At each problems they were very fast to act, and they resolved everything.
The flat is good, even if some points could be ameliorate.
I recomand this flat, mostly if you have a car and you want to travel a bit around lisbon, because the mains roads are near and you can leave the city in 5 minutes. To go to the city center, 10 minutes by bus, 45 minutes by feet.
