It was our first place of stay in 2 weeks long trip through Spain and this place truly delivers. Location is very convenient. First of all - it's close to everything in Centro so you can easily walk anywhere in 10-15 minutes. At the same time it is located in quiet part of downtown Madrid thus you're not bothered by noisy crowds sitting in local cervecerias and bars.
Apartment itself was cozy and clean and had everything necessary for few days of stay. Laundry is available in the building as well. Check in process was a breath as well as check out.
Carlos and Victoria were super helpful and sent in advance all necessary instructions regarding everything (transportations, logistics, check-in/out, request if anything missing at apartment, etc) so we were completely confident our stay is going to be awesome. And it was.
Highly recommend this place for anyone planning to go to Madrid!
