After 3 wonderful days in Lisbon, we can only recommend staying at Malgorzatas place. The room is very central in Biaxa-Chiado, only a minute away from the subway, 2 minutes away from the Praca de Commercio and the old town Alfama is nearby. We came about an hour late, but Malgorzatas mate Carlos waitad for us paitiently. The room with 2 bed in it was very nice, clean and cosy. It's even got a small balcony and fresh towels as well as a sweet small soap we're waiting for us. The kitchen and the bathroom were also clean, and there is everything you might need - and if you're missing something you need, just write Malgorzata, she will answere within minutes and help you out. :) The other flatmates and Malgorzata are very kind and easygoing. The price is, in our opinion, very fair for what you get, so don't worry and don't hesitate to much ;)
PS: as we arrived back home, my friend realised she probably left her addapter for the iPhone charger in the room, so we wrote to Malgorzata who immediatley checked the room, found it and sent it the same day back to Vienna.
So, as I already said, we can only recommend booking a room at Malgorzatas place!
Best wishes to you guys (Malgorzata, Roberto, Carlos...) from Vienna and thank you for a very nice time!
