INCREDIBLE LOCATION!
This place gets 4 stars because Glenn and Paulo were so responsive and helpful, and the location is incredible. They deserve high marks as hosts.
However, for those who would like more information and take their time reading through the reviews, there are some things that weren't great about this place for our particular situation (two adults and one 15-month-old staying for 2.5 weeks). If you aren't staying that long, or aren't planning to cook much here, or don't have an infant...none of this might apply!
The place is VERY SMALL, and in the summer quite stuffy. The back patio is TINY, and directly beneath the units above so not very private or welcoming. Plus, in spite of our hosts' very kind effort to clean the drains...it smells like sewage rather strongly. The stove is pretty slow...and seems to have trouble heating more than one burner at a time with any vigor. The entryways into the building and into the unit are very short (I'm 6'1" but still) and kind of cramped. The dear older woman across the hall has her TV on full volume until at least 10pm each night, and you can hear every word. The internet works essentially ONLY on the very far corner of the couch near the window and nowhere else in the unit, and even in that one place it is highly unreliable and slow, likely to drop off at any point. Unfortunately, due to COVID, there was no laundry facility/washing machine available --which was not mentioned on the ad for the place!--so we ended up at the laundromat across the street (a tip: go to the bank to get 1 Euro coins...no one else likes to share them!). Upon complaint, Glenn explained that the laundry issue was offset by a 30% discount on the rental price...which was likewise not mentioned up front. So I'll take his word for it...
Let me reiterate: the location is fantastic. Praca das Flores is right outside, surrounded by lovely cafes. Jardim de Principe Real (with a great popular playground and the absolutely incredible organic farmer's market every Saturday!) is a very short walk uphill. Jardim de Estrela, perhaps one of the most wonderful parks in the city, is 10 minutes by foot. And of course the peaceful, tree-filled botanical gardens are only about 5 minutes walk. We really recommend checking out Ceres bakery (100% sourdough baguettes served HOT!), Nannarella gelato, and the chocolate cafe Bettina Corallo. There's really so much good food in this neighborhood, and plenty of nice spots to enjoy a picnic.
