Apart3 hosted by Luis is really one of the best places you will see in Lisbon. I will explain.
If you look at the price as compared to renting out in bed and breakfast or hotels with breakfast only, there is no comparison. Luis' place is cheaper. Now if you take it one step further and go for a 3-meals daily hotel you are tied down to eating at the hotel and getting to the hotel in time for lunch and supper and sightseeing in Lisbon has no time. So my suggestion to you all is to visit Luis' Apart3.
Located in a very peaceful neighborhood of central Lisbon, you can walk to Praca dom Pedro IV in ten minutes, you can walk to the metro station Anjos in 2 minutes and connect to any metro line you want, you can walk to Lidl food store in less than 4 minutes. The joy of Luis' place is you have everything inside - fully furnished with washing machine, dishwasher, dishes, pots, pans, forks, knives and most importantly a fully functional refrigerator (including deep freeze). The apartment has 3 rooms with all sheets, pillows, pillow cases, and blankets. There are 2 balconies and the apartment is full of sunshine from 06h00 until after 20h00!!
You will physically see the host Luis twice - once when he receives you and once when he takes the keys upon departure. However, he is 100% available through e-mail/AirBNB connection and always responded to messages sent within a few minutes some times but always within 1 hour. Any question you have, he will have an answer. We asked him about getting a taxi to come to the apartment at 04h00 to take us to the airport (our departure time was 06h00) and he did it for us. He came at 03h45 to take the keys, speak with us, ask us questions whether we liked it or not. Luis was very honest, open and friendly. It was genuine and not fake, you can see from a mile away.
Luis also prepared us supper (a cod fish specialty of Lisbon) plus other delightful food with shrimps. He put some items in the refrigerator for us too.
Overall I would recommend Apart 3 for groups of 6 for the following categories:
1. One family of 6 with 2 adults and 4 children;
2. Three couples (6 people) with no children;
3. Two families with one child each (3+3=6)
