Everything was more than fine! Thank you :) The location is just perfect - in the very centre of Madrid. Walking distance to all main attractions (Plazq Mayor, Royal Palace, Prado Museum, Retiro park). However, one must emphasize that at the same time that could be a disadvantage for some people as the street is very busy and loud, even at night. We were staying with 2 children and it has NOT been a problem for them (they have hard dream) but I can imagine that for some children that could be inconvenient. For party lovers - go for it!
The flat was very clean and 2 separate bedrooms with a seperate tv room is very convenient. Contact with the owner very good, quick responses and clear messages. To sum it up - perfect value for the money - would stay there again! :)
