I stayed at David's place with three of my friends and it's exactly as in the pictures and the description; it's quite small and very cosy and the location is to die for - it's really easy to get everywhere from there. There's a tram station, a metro station and an elevator nearby, and a great place to watch the stars above Tagus river in the evenings just a couple minutes away. There's a supermarket and a pharmacy nearby, too. There's everything you might need in the apartment. We had a couple of technical problems, but we solved them ourselves or with David's help. Overall, I'd recommend this place to anyone and will certainly stay here myself next time in Lisbon :)
