Simply excellent!! Staying at Alvaro's was the best decision. The flat is lovely, with old Madrid charm but refurbished with an eye for modern design and detail. All the comforts you might need and more, including TV and WiFi. The location is superb... we walked everywhere. Plaza Mayor is within 5 minutes, just as the trendy Plaza de Santa Ana. Puerta del Sol and the museum quarter is a 10 min walk. Metro Tirso is literally on your doorstep, along with some cozy terraces and a supermarket across the street. The flat is on the back so you won't get any noise from the street. Our host was really friendly and helpful and left maps and tips of where to go and what to do in Madrid, he even left us bread, fruit and a delicious chocolate bar :) Much better than any hotel. The stairs up can be a challenge with a big bag, but it's really worth it!!
Gracias por todo, Álvaro!!
