We had a wonderful time staying at Irena's apartment. The location was perfect and by far the best amenity. We were only a 5-minute walk from Plaza Mayor and the La Latina Metro station. The apartment was right next to a lot of great restaurants and beautiful architecture. To speak a little on the comfortability of the apartment: the bed was quite firm but we managed to sleep through the night, the flat was quiet even though we were four floors above a bustling street, Irena provided a hair dryer and a straightening iron for people who would like to leave those items behind, the air conditioner works well but the fan provided is a little noisy, the apartment is all tile so bring a pair of slippers to give your feet some cushion after a long day of sightseeing. Overall, we would definitely stay here again and recommend the apartment to anyone who wants to visit the beautiful city of Madrid.
