The place is in a good position, very close to Avenida metro (underground) station and a couple of relatively big food shops. Christophe has definitely put good effort when we have asked for extra pillows and for other small adjustments. The flat is very clean and the kitchen and bathroom are small but well equipped. The wi-fi works well and is reliable. A fan is available.
However bear in mind a few things before booking:
1) The bedroom does not have a window and you're very much on a street (front) and looking at the neighbour's balcony (back) so keeping the two main windows open is not always an option and it gets quite hot. I should have realised that myself from the pictures: I would have not booked it if I had known the floorplan.
2) The table and sofa are really not comfortable: we have found it very hard to relax in the evening.
3) We were given only two very soft cushions for the bed, Christophe has kindly bought us some more pillows on the second day (no pillow cases though) but extra pillows should have really been there in the first place. The bedsheet was actually a duvet cover: it is not a bad thing per se, but it does not give a good impression either.
4) There is no storage for clothes, with the exception of some shelves which are not well located (they're above your head in the bedroom). There is a cabinet in the bathroom you could potentially use and there is a closet next to the sitting room but it's more the sort of place you put the hoover in.
5) The building is old and the flat is small, the walls are thin and there are very few sockets and none of them are placed conveniently. The flush in the toilet works intermittently.
6) There is no washing machine (this is mentioned in the description) and no drying rack. Christophe's suggestion was to dry our clothes and towels in the aforementioned closet as this has a tiny window but it really isn't practical.
7) The street can be quite noisy, our impression is that it was mostly AirBnB flats so you have good chance to live near a group of lads playing loud music as well as often breathing cigarettes' smoke from the neighbours and people standing in the street. They're also doing works next door. It is much quieter on a weekend night, probably because everybody goes out.
8) This is simply not a true statement: "The apartment is also equipped with all the modern technology and appliances you could use for your optimal comfort.". The "technology" does not go beyond the wi-fi and the dishwasher (i.e. the tv is not a smart tv, there is no air con, no washing machine, etc.). For me the description of the inside of the flat is misleading.
9) The place is owned by a company, so it is really basic: we have found nothing nice or thoughtful inside, like a book, a bottle of water or juice already in the fridge, a deck of cards to play, anything would have made it a bit better.
10) Finally, I have not been happy at all with how my check-in has been handled, as Christophe, instead of greeting us as per description, shared my private phone number without my consent with his friend / colleague, who performed the check in. I can see he has done it in good faith, but it just shouldn't happen as it didn't make us feel safe.
I would recommend the place if you are staying in the city for a couple of nights and just want a bed to return to after going out for drinks or clubbing.
I am really puzzled by the many 5 stars reviews, perhaps it's just not the place for me, although I have been in several tiny AirBnB flats and this was the only one I really dreaded going back to in the evening.
