We highly recommend Nuria's apartment. Ideally situated just off the Gran Via, it's walking distance to almost all of Madrid's attractions, and the area is full of tapas bars, restaurants etc. The apartment itself is immaculately appointed and spotlessly clean. Double-glazed windows ensure that, although in a lively area, the apartment is very quiet. Nuria herself was lovely - only too happy to chat and suggest places to see and things to do. We would definitely stay here again if we return to Madrid (and hopefully we will!).
