The Good: We were lucky to get a room with actual windows, so it was light and airy whenever we leave windows open, and that is helpful because the heater fan they provided did not serve any cooling function. Lots of kitchen tools (pots, crockery, utensils) but no kettle. Shower was amazing. Bed was comfy. Enough plug points scattered about to charge our devices. There's a laundry room with ironing board. Responsive to WhatsApp messages. Location is central in Alfama with tramstops outside, and Uber was convenient. Plenty of nearby restaurants and mini markets.
The Bad: Only 3 small poor quality toilet rolls were provided, you will NOT get any extra even if you asked nicely. There was a dead cockroach in the bathroom and floors feel grubby. Blankets and cushions smell stale. No housekeeping no matter how long your stay is. It's right beside a tram line so very very noisy from 5am to 1am, so be prepared with earplugs, and it's a very rowdy area anyway full of tourists. No instruction on how to turn the hob on. In the courtyard outside the compound watch out for dog poo, lots of it. Our first night there, someone banged at at the gates opposite all night long, demanding 'Meera' to let him in.
Conclusion: If you're rough and ready type, this would be adequate for your needs, especially if you're outdoors most of the day. But if there is a hotel with comparable costs I'd pick that instead next time for the convenience of unlimited loo rolls and simple housekeeping.
