Isabel's place was fantastic, it was walking distance to the centre of Madrid, and had loads of cool cafes and shops in the immediate area. The kitchen was well equipped to cook in and everything was clean. Isabel was super quick to answer all my queries and was very accommodating for our check-in/check-out times. Thank you!
The only reason I gave the flat 4/5 stars rather than 5 was due to the fact that, with the flat being on the third floor, it remained sweltering hot during our whole stay with only a fan and a dehumidifier to cool us down which unfortunately was very ineffective. Cue lots of cold showers in the middle of the night to cool us down!
