We have stayed for a couple of days in the beautiful flat of Amrita. Overall the Flat is very nice and new. Also we perceived the Flat as quite clean and well equipped with designer gadgets. However there are constructions for the underground metro right in front of the house. As the construction work continued also during the night between midnight and the early morning, it was not easy to sleep. So my recommendation would be to provide ear plugs for the guests of the house, in order to ensure a sleep-friendly environment.
Nevertheless I would recommend to any visitor the flat, as it is quite central, you will be able to find nice coffee places (for pasteil de nata) and bars & restaurants (for steak sandwiches) just within 2 minutes of walking.
