Wow! What an apartment! My wife and I stayed here for 4 nights and we couldn't have been happier. The apartment is exactly as it looks in the photos - spotlessly clean, stylish interior design , ridiculously comfortable and very well equipped (hair dryer, dish washer, iron, washing machine, coffee machine, smart TV, Bluetooth speakers, air-conditioning, everything you could need and more).
Though bear in mind it's on the 4th floor of an old building, so there's no lift. Wasn't an issue for us, but be prepared for it if you have mobility issues.
Location was perfect too. A few minutes from Baixa-Chiado Metro station and right in the Barrio Alto - so close too an overwhelming range of bars and restaurants. Though it is on one of the quieter streets so the noise from nearby revellers never disturbed us. Being on the corner of main street Calçada do Combro meant we had quick access to a supermarket, bakery, fruit shop, ATM and the tram.
We had the pleasure of dealing with António for our booking and the guy is an absolute legend. He quickly answered any correspondence we sent about the apartment or getting around Lisbon prior to going. And he was just friendly and helpful when he met us to check in. He gave us loads of info and tips about places to eat and see, explained all the features of the apartment and even let us drop off our bags before check in. He also arranged for a taxi to collect us on our last morning to get us to the airport. He really couldn't have done more for us and made us very much at ease in the wonderful accommodation.
Very highly recommended. We'd definitely stay again.
