We loved our stay at Rui & Bernardino's place - the location was perfect in the heart of Alfama with a great buzz around (although we were never kept up late or woken early - noise from the street was not an issue during our trip). The view out across the Tagus was amazing - we were lucky to get beautiful sunsets and sunrises when we were up early enough. The flat is small, but this is clearly outlined in the flat description and the price is very fair given the location. We would strongly recommend the flat to anyone visiting Lisbon provided you are OK with lots of steps and a compact living space!
