Hugo was very kind and welcoming with me and my girlfriend: he picked us up at the airport and showed us some useful spots on the way to the flat, giving us a lot of information about Lisbon. There was also a good bottle of red wine prepared for us!
The apartment is really amazing, equipped with everything and even bigger and better than it looks in the photos. Located in the old neighborhood of Alfama, it offers a stunning view on the riverside and is very convenient for exploring some of the city's major attractions (like St. George Castle) by feet. It is very very quiet at night, so it's easy to sleep well. It's also pretty close to minimarkets, restaurants, bars and means of transportation.
Definitely recommended if you want to get a taste of the heart of Lisbon. In addition to this, Hugo and Silvia are really great hosts and always ready to help!
