A friend and I stayed at Elvira's apartment for 3 nights, the apartment is as shown and described. Great value for money given it's location, close to a tube station and walking distance (20-30 minutes) to Madrids central attractions and sites.
Elvira gave some extra tips for places to eat in the local neighbourhood which we visited (the bakery a few times!), they all had a friendly vibe and were really welcoming, this is a major plus when in a new city.
The communication with Elvira was great and she even checked we were settling in after the first night.
