We stayed in this apartment for 4 nights in late May, early June. The temperature outside (25-30 degrees Celcius) did not affect the apartment and especially the bedroom was cool and dark, which was perfect for the night. The living room is really spacious. We did not use the kitchen because eating out is fairly cheap in Lisbon, compared to Northern European prices. Tram 28 (the tourist tram) has a stop around the corner. We especially enjoyed the street cafe at the Miradouro Sophia de Mello, a 5 mins walk from the apartment. It has a great view over the city and they serve nice, cold beers. Claudia is a really friendly and helpful host. When we checked out, we could leave our luggage in her own home around the corner and pick it up during the afternoon, which was super convenient for us. We can really recommend staying in this apartment in Graça!
