Guilherme was a great host, friendy and really fast in communication. His place has everything you might need for short or even longer stay in Lisbon. The apartment is just a minute away from Largo de Rato, which is a big crossing for several bus lines that get you anywhere in the city. There is also Rato metro station there, the last station of yellow metro line. I would recommend staying at Guilherme place to couples and families, you will feel as if it's your other home in Lisbon!
