Ana e Ricardos place was perfect for my stay in Lisbon. Walkable area, many restaurants and shops around and close to train station, grocery store and nice view of the water of where cruises dock their big passenger boats.
Remember that to get the beautiful view on the top floor, you must go up many stairs to arrive at this apartment. Bring luggage that is conducive to the many stairs. The building is quaint, old and feels like it should in Lisbon, but keep in mind the walls are thin and you have neighbours all around so if you can’t handle a bit of noise, be warned. The beautiful waterfront is steps outside your door and a 5 minute walk from the famous Square Praca de Comercio, overlooking the water. I recommend staying here, for a single traveller or a couple!
