Wonderful 4-night stay, thoroughly enjoyed it!
Great location in Belem, away from the busy tourist area yet only 10-12 minutes walk away. Easy to find on Googl Maps. Around the corner is a mini market and two Portuguese restaurants (both open late).
I have nothing negative to say about this apartment, it is perfect for the price. I would totally live here!
(The noise from upstairs might be a problem for some but it wasn't for me, it's what I expected for Lisbon or typical shared buildings in Europe.)
Very clean. The bed, sheets, and pillows are very comfortable. Living room is spacious and tastefully decorated. Kitchen is well stocked with everything you need. Bathroom has plenty of toilet paper (some places really skimp on this). Yes the shower stall is small but it wasn't a problem. Plenty of hot water and water pressure was consistent. Fast (30+ Mbps) and stable wifi.
Overall the apartment is very well stocked, like the owner(s) actually lived there.
Communication with the host was easy, check in was easy as well.
Highly recommended.
