Edgar was very nice and helpful, sharing some tips and giving me a quick drive around the neighborhood.
His home is located in the Belem area, which is a popular one day visit. Staying here, you would spend the day in the city and come back to Belem, instead of the other way around. There is a bus stop down the street that takes you to stations in Lisbon and are inexpensive.
The city of Belem is an attraction, so there are many restaurants, however you will not be able to walk there, much less attempt to 'hike' the steep hills back, very typical of Portugal, and predominant in Belem. Uber is only a few euros ( and the only option, really). Just make sure to get a phone chip, so you can use the app. Tip: go to the Vodafone store as soon as you get off the plane, you will feel lost without wi-fi, especially if away from the city center.
As stated in the listing, this is an old 'grandma's' (actually Edgar's) type house. The 'loft' is very clean, as it is the rest of the house. The staircase that gives guests access to the loft can be challenging for big people and anyone with heavy luggage, as it is very narrow.
