Everything was fine in the apartment, which is very cosy, light and in a perfect location - in just a 5-min walk from Nueva Numancia metro station.
Nelson is a great manager/host. He was amazingly helpful and attentive to all my requests and assisted very promptly.
There were two main negatives - there is a disco in the house next to this one. It may get very noisy at night and people shout under your windows, which makes it difficult to get a sleep. Another “bad” was a bathroom. It is small and splash water everywhere when you take a shower. Nelson, I would highly recommend having a shower cabin there. This will make your apparent a real nugget !
I would definitely recommend and will come back again in case I come back to Madrid again.
