Sonia's apartment is beautifully appointed, very modern with plenty of space. Whilst it's a little ways out of town, there's plenty around (Bufete Fase is a few minutes away and did a great Francesinha). We didn't use the metro, but it is very conveniently located near by. One warning, if you park near by to orient yourself (this was just until we'd checked in), be warned that all on street parking is paid and heavily monitored.
