What a great location! My wife and I, we stayed 10 days at Konstantinos' apartment, and we really enjoyed the time! Konstantinos is the best host you can imagine. He waited for us at the apartment and explained everything we needed to know. Furthermore he gave us priceless recommendations, e. g. where to find the best bakery, coffee shop, market, flamenco show and so on. Everything in the apartment was very well prepared (bed, towels etc.). The pictures and descriptions delivered by Konstantinos are very realistic and give you a good idea of the actual situation. The kitchen is very well equipped, the apartment is spacious and very quiet, and it's conveniently located near the famous museums Prado, Sofia Reina, CaixaForum, the barrios Huertas and Lavapies, Atocha train station, the botanical garden and Retiro park. I highly recommend this place and would be delighted to check in here once again some day.
