Not sure why they call it the Brown House, it's closer to Beige. Just an observation. I stayed in the ground floor bedroom with a double bed, desk & chair, closet and that's it for furnishings. Room has AC, plenty of outlets, and it's own toilet and shower connected to it. Wifi worked great. Didn't try using the TV so have no opinion about that. Kitchen is small but has the basics: oven, stovetop/hob with 3 burners, basic pots and pans and utensils, and a washing machine. There is a drying rack out front of the house. No coffee maker or toaster. The kitchen and the living room are one and the same. It a small tight space but adequate for its purpose and for temporary living. You do share the common space if the upstairs room is rented out during your stay.
Very close nearby is a small grocery store Mini Preco about. 3 min walk. There's a larger grocery store Lidl about a 8-10 minute walk. The metro is about 5-6 minute walk, station Heroismo, and same for the train station 5-6 minutes.
I liked the apartment and sharing it was not an issue for me. The neighborhood seems safe, I never felt any type of danger or shenanigans was about to occur. I came home late on several occasions and never had any issues with safety after dark.
My only con would be there is not very much space to store things in your room. There's about 10-12 hangers in the closet and then there is nowhere else. You can put somethings on the bottom of the closet but storage space for clothes and any gear is limited.
Also they allowed me to check-in early and check-out late. Not sure if this is always available but I really appreciated it instead of standing outside in the rain until the designated time posted on AirBNB.
Overall I give the place a thumbs up. Good place for an extended stay where you can cook some of your meals, and save some money, and do your laundry for free. Cheers!
