We had a wonderful stay at Alessandras place in Madrid! She was such a nice host: the day we arrived, our flight was delayed, but she stayed awake and communicative until 11pm and even cooked a Spanish tortilla for us and served us Sangria after our arrival.
The room was very quiet compared to the street (4th floor) and clean. Since there are a lot (a LOT!) of great restaurants and tapas bars near by, we didn't cook during our stay. Ale showed us two wonderful bars near by on the first night and a nice restaurant for our last evening in Madrid.
I would definitely stay at Ale's again!
