We enjoyed a wonderful stay at Ricardo's grandfather's house. We were honoured to stay for a full month, so really got to know the place well!
There are many positive features to this airbnb:
The best part is, of course, the garden. It is fully enclosed, so very secure for my toddler to play. We were also there during clementine season, so had the added treat of fresh fruit for our breakfast every day. Even in November/December, the weather and sun were nice enough that we had many lunches at the tables outside.
We were very happy with the location. If you are looking for a place in the centre of Lisbon, this is not it. However, Belem has lots (and lots and lots) to do, all within walking distance, and is well-connected to Lisbon, so we actually preferred it to the busy city.
Ricardo was there to greet us in person, and was always available throughout the stay. We had a little glitch with the water heater, and he was prompt and helpful to fix it. I also made a comment about the bread he'd offered us at our arrival being so good, and he had a fresh loaf delivered to us that very evening! He offered local tips about what to do, particularly with a young child, that were appreciated. When my father passed through town, he was very kind about letting him stay as well, even though it was not originally the plan.
The wifi worked great, even fast enough for streaming music on the bluetooth speaker provided by Ricardo.
The beds are both king-sized and the mattresses feel new (not lumpy at all). There were tons of fresh linens at the house, nice duvets, and many pillows to choose from. I would say the bedding was definitely above average for an airbnb.
A few things to note:
The house I would describe as rustic and simple - you can feel the charm of its history. There isn't really storage for clothing (i.e. no wardrobes or dressers), though it has been updated with some modern amenities such as a dishwasher, washer/dryer, and Nespresso machine. When we arrived, I think nobody had been staying there recently, so there was a bit of dust and some insects in the cupboards.
The house is on a residential street, and the neighbours are quiet. There is a loud truck (perhaps picking up rubbish?) that passes at about 3am each night. As the windows are single-pane and give onto the street, this did wake us up a few times, but heavier sleepers might not notice.
Overall, we were very satisfied with our stay here, and would happily request to return if in Lisbon in the future. I recommend this house particularly for families with young children.
