This flat made a great base for our long weekend in Madrid. It is quite small, but worked well for us. Everything was clean, the bed is comfortable, the shower was great & importantly the air conditioning worked well (although beware that it is right above the bed)! The location is also brilliant, just off Gran Via in the busy & exciting Chueca area, but it is not noisy in the apartment.
There were a few strange things like no kettle in the kitchen & some of the pans in the kitchen don't seem to work with the induction stove. We also couldn't find the ironing board, until we realised there was an extra section to the grey wardrobe by the wall that we only worked out how to open by accident.
Communication is not through Manuel himself, but the Minty company, which wasn't always good. For example, we requested an early check in and were told we’d get confirmation at least 24hr beforehand but only heard from them again on check-in day. However, everyone we met in person was friendly and helpful.
Overall, I would definitely recommend Manuel's place for anyone wanting a cozy base in central Madrid.
