We loved this place! We stayed in Room Baby. The apartment is located right downtown and on a main street - easy to access many attractions and about 20 mins from airport. The room is very private and we did not hear any of the other guests. The common area was not close to our room. Though the balcony was on a busy street, it offered good noise reduction. We arrived early and was able to drop off our luggage for the afternoon. Would definitely recommend staying here for anyone travelling to Lisbon.
