Great flat in a great location to explore Madrid, we didn’t use public transport once as everything was really close. It’s up in the attic so it does have quite low ceilings but we weren’t in the flat much so it was perfect for us for a few days in Madrid. The facilities were nice and comfortable, very nicely decorated.
There is a big construction project going on next door so there will be a temporary noise issue if you’re staying in the week and if you’re a light sleeper. It didn’t bother us as we were up early anyways but can be a problem for some people although for the amazing location inevitably there will always be stuff happening around!
