I stayed with Elsa for 2 nights recently. Everything was just as advertsied in the listing. The building is close to the Metro and Elsa explained to me very clearly the easiest way to find it as i arrived from Atocha. The room and bathroom were both very clean with the nice touch of shower gel/shampoo provided. I had to go in to the airport to do a PCR test so decided to walk in, it took 15-20 mins. When i left i took an Uber directly in to T4 which cost 8 Euros (T1-3 is only about 3-4 Euros). Elsa and Gustavo were very kind and friendly, we had some nice chats about life and different places. There are 2 italian restaurants right outside the building which are handy. If you want a place close to the airport its a great option.
