We couldn't have had a better stay. We were in the apartment for over a month and we felt totally at home. Chiho and Nuno are super quick to respond and they genuinely care that you have a pleasant stay.
There are loads of restaurants, bakeries, markets and gyms close by, we found everything we needed just minutes away.
The apartment has all necessary amenities, the a/c & heater work perfectly, there's a big tv with cable, pans and pots in the kitchen, all windows are double-glazed and with electric blinds, everything you need, really.
The neighbourhood (Arroios) is not really touristic (which we loved) but you can easily get to the city centre by metro (or walking if you're up for a ~30 minutes walk).
I totally recommend it and will definitely come back if I have the chance.
