Ines and Ricardo's flat is a great place from which to explore Lisbon. They were both easy to get in touch with and answered all our questions promptly before our trip. Ricardo welcomed us to the flat himself with lots of great tips on good restaurants and sights - do yourself a favour and take them up, we had many lovely meals while there thanks to his recommendations.
The flat itself is quite central - about a 5 min walk from the nearest metro, and an easy 15 min walk from downtown Lisbon. It's really comfortable and equipped with any amenities you need. Bed was super comfy and the neighbourhood's really quiet at night - great for a good sleep after a long day of exploring.
