Irene&Joana's place was really great. The apartment is quite spacious, very bright, very confortable, and it has pretty much all the basics, and more (for instance, as a coffee drinker, i was pleasantly surprised to see that the kitchen was equipped with a Nespresso machine :) )
The location is simply perfect: the great and old Alfama neighborhood, quite close to the airport (easy to get there by metro), close to S. Apolonia train station and Metro, 20 min on foot to the city center (Praça do Comércio) and many many other tourist attractions. Actually, except for Belem and the Ocenario, we walked to all the places. There was also a direct bus to Belem and the Ocenario, which really made the difference for our trip. I was also happy that despite the warm weather (we came around mid August, so the temperatures were quite high), the flat remained cool both during the day and during the night (for instace, if it gets a bit noisy during the night - sometimes they clean the streets or pick up the garbage - you can close the windows and still be able to peacefully sleep). There are also a lot of local restaurants and mini markets were you can buy a great variety of food at good prices. More importantly, Joana was a really nice and helpful host and she promptly replied to all our enquiries. All in all, we had a real great time in Lisbon, and this flat really made the difference.
Muito obrigada, Irene & Joana :)
