We spent 4 nights here and the location was perfect, super close to metro and supermarket and very central to explore Lisbon. We were 8 and we appreciated having 2 complete bathrooms and a separate toilet. However it was not clear to us that one of the bedrooms is accessible only through another bedroom, which forced us to use the living room as an extra bedroom, and it was not ideal. The flat is on the first floor, just above a very nice bar, which however plays music that you can hear from the flat. Beside Halloween night though, they are open only during the day, so if you don't need to sleep during day time or you don't mind music while sleeping it's not a big deal. At night I found it to be pretty quiet neighborhood and also not a lot of traffic.
