We were impressed with this apartment. Maria cares a lot about providing a lovely place for you. Its a stylish, v. clean, bright ground floor apartment in a real neighbourhood rather than a touristy hotel complex of which there are many in Lisbon.
The beds are big and comfortable, the shower is hot and easy to use. The kitchen has utensils for cooking and a big fridge and dishwasher although we didn't use it. Theres everything you need for a short stay in Lisbon. Its also near a Metro station Intendente which is useful for getting around.
There are people living above you in this block so you do hear them coming in and out and moving around upstairs sometimes, but the street itself is quiet, theres no traffic noise. Lisbon is a noisy city so you're not going to find total quietness anywhere.
