We had a great stay at Rita&Helder's place, we enjoyed Lisbon by walking - the location is excellent and you definetely do not need a car at all - you can just walk. There is also a drawback of that, the road is quite crawded and noisy and we had to sleep with earplugs. One more comment regarding the bad, either i am not a tall person, just 1.76, the bad was more or less small even for me. If you are more than 1.80m, i do not think you will sleep too comfortable. Besides that, everything was perfect, great communication and nice city to visit!
