Our family of four stayed at Frederico's apartment in July. It's a beautiful place with lots of space and is very well equipped. The bathroom and kitchen had everything we needed and the bedrooms were very comfortable with lots of storage. It was hot in Lisbon during our stay but the apartment was cool, and there is air conditioning to cool things down even more. The apartment is located in a great area, 5 minutes walk from the top of the Ascensor da Bica and 15 minutes from the Time Out market, and with some especially great breakfast places (The Mill and Break were our favourites) just around the corner. Check-in and check-out were really easy and well organised and Frederico is the most charming and helpful host I can imagine. He was extremely accommodating, provided us with some great restaurant recommendations and responded really quickly if we had any queries. I would definitely stay here again, highly recommended.
