Hi! I stayed there for a few nights in late May at the end of a 6 week trip to Europe. I decided to splurge in the last few days as it had been budget all the way, and I wanted to finish the trip in style. It's a luxurious hotel just a few steps from Plaza del Sol and a stone's throw from Cortes Ingles which is very handy as they have a supermarket there. My single room was very big, carpeted, air-conditioned with two double-beds stuck together. The room style is subdued and classic. The mattress was fabulous. There's tv with movies, a mini-bar, very comfortable furniture and a table you can actually spread any reading or writing material. The Plaza San Martin is quite noisy at night but the double (or triple) glazing effectively kept all the noise out. The room was soundproof, and after lots of pleasant but noisy budget hotels, I was in heaven. There were lots of extra blankets in the cupboards as well as a safe. The bathroom had toilet, bath and shower and bidet as well as all the 'stuff' that comes with that class of hotel: comb, soap, etc. Lots and lots of thick towels. There is a 6-person elevator. Most of the staff speak English and are very helpful if a bit over-formal (comes with the territory, I guess). My room came with breakfast which was a buffet. Lots of fruits, toast, various meat sandwiches, etc. coffee and tea. However, I didn't really find it all that filling. It takes an egg not fruit to get me going in the morning! But I'm being picky. Hope this helps! Bon voyage!
