This was a great stay. Aside from being a lovely, super-clean and well-located property, it is very well managed. The hot water is on point! Also, this is possibly the only AirBnb we've stayed at that didn't just give 1 single towel per person - but an actual SET. Like people actually need if staying more than 1 night. There are also plenty of tea towels in the kitchen instead of the one or two most places stock as if they don't want you cleaning up any messes, haha. (These things are small but can be quite annoying for a multiple night stay.) We have zero complaints - but I will note a thing or two here just for information, especially for families with small children.
That is, the kitchen is equipped enough to get by, but not really for properly cooking meals in. Also, if your kids naps during the day, note that the business on the floor above can be quite noisy (thudding, etc) in the afternoons. Very possibly some white noise would take care of that but just so you know what to expect especially if your kid is a light napper.
In all other ways it was great for our kiddo. She's just 2 and in a hilly town like Lisbon it was nice to have (1) an elevator and (2) a location that is ideal for tourists, yet quiet and also didn't involve walking up hills and lots of steps every time we went home.
