I would not stay here again.
It starts with terrible check-in, be aware that when you arrive in Lisbon (with all your luggage) you will have to travel all the way across town to get the key 45 minutes each way, absolutely ridiculous and very inconsiderate to guests especially if this is not available information before booking.
Kitchen is not made for cooking, as you cant use the cooker without the power going out, we called the contact but they clearly didn't care and said we were using too many appliances but we were using only the hob to cook pasta. apart from that, expect broken pans and bring your own kitchen necessities like oil, salt & pepper, washing machine detergent, and a tea towel.
Also the sofa is broken with a massive dip in the middle, does not make for a comfortable evening.
The roof leaks through the boiler when it rains. In the bedroom there are also no curtains, this means that when the neighbors are home their light shines directly into your bedroom, expect to be sleeping in full brightness like a prison. Tip for the next people: you can trap the edge of the jumper in the window and make a make-shift curtain.
The shower is also semi-broken, and the walls are dirty and at one point a floorboard nail went into my foot.
On the positive side, the location was great and the bed was fine.
The place seriously needs some attention. This place is worth half the value it is listed for.
