Marius' apartment is simply great. The view is stunning, even better than the pictures show! The place is nicely decorated and in all very cosy and comfortable. Communication with Marius was very easy, and questions were quickly resolved.
The flat is very well located in walking distance from the main sights and areas such as Alfama and Barrio Alto. Public transport around the corner to Belém and Sintra. I would definitely recommend this to anyone traveling to Lisbon!
