João is a fantastic host, and his property is very clean and spacious! Everything was as described in the posting, and João was also very kind to review my itinerary with me (to give pointers). He also went the extra mile in helping to arrange for an early morning taxi for my party, per my request.
The neighborhood is very safe, and in close proximity to many excellent food venues (e.g. Mercado de Campo de Ourique, O Magano, Pastelaria Aloma) and markets.
João is a very friendly and generous host, and I would not hesitate to stay at his property again on any future trips to Lisboa.
