Had a great (short) stay i Lourenco's appartment and can absolutely recommend it to everybody. The pictures describe it well, everything you need is there and is clean and well kept. Although I didn't meet Lourenco in person, his reactions are quick and helpful. He arranged the key exchange through a friend (Marco), who also was really helpful.
Nice neighbourhood as well, quit and close to the more lively parts and excellent restaurants closeby, a very good bakery and a small supermarket.
