This is a comfortable clean apartment in a great location. However we had a miserable check in , being left on the footpath outside for 45 minutes,. We made increasingly frantic phone calls to people who spoke little English while we speak no Spanish. Despite repeated prior written advice that we would be met outside the building, we were eventually found by a pleasant young woman who said she had been waiting inside and we should have rung the bell. Not helpful, since this is a large building with many apartments on 5 floors and we didn't know which was ours. We had a brief introduction, with limited English on her part. There was no written information in English provided about the apartment, appliances or area. However, the Tourist Information at Plaza Mayor has excellent maps and is helpful. The apartment itself is fine. The shower is excellent and the aircon worked on the very hot day we arrived. It wasn't needed after that, as the apartment was cool despite heat outside. There is some noise from neighbours.. Thoughtful touches include provision of laundry and dishwasher detergent.
There is an excellent cafe/bar downstairs where the staff are friendly and helpful. Highly recommended.
While there is a lift in the building there are also 3 small flights of stairs, as well as 2 sets of locked doors, which can be tricky if you have heavy or bulky luggage. If you can manage these, and achieve a reliable check-in, this will be a fine apartment, because the location could not be better.
