4 of us (2 couples) stayed for 2 nights at the Mi Casa Inn apartment. We arrived earlier than expected and Daniel referred us to "lock and be free" service where we could pay a small fee to hold our luggage which was very convenient and appreciated! The apartment is very modern with everything you will need. The location was excellent for walking around Madrid and seeing the sights. It was very close to Plaza Mayor...you must try the tapas market just west of Plaza Mayor...great food and atmosphere! The large balcony was excellent for sitting out and enjoying some wine and sun (or on cooler, but warm nights)
We would definitely stay here again and recommend it to others heading to Madrid.
