I really enjoyed the bright apartment and was even able to take advantage of the balcony in January. It is quite small but more than sufficient for my solo travels and could accomodate two people. The kitchen was not as well stocked as it could have been, I left a bottle/wine opener for the next guests. It is very close to the Almendras metro station with a 10-minute ride to the Sol metro stop in the middle of everything. Bars, cafes, stores are all incredibly close, as well as access to the path along the river that I walked almost every day.
One thing to note that is very important - the address on the building does not match the address on the apartment. Unfortunately upon landing I realized my new phone service does not work in Spain. I sat outside where I thought it would be with my luggage thinking that someone would come along and recognize that I was there to be let in, but the person checking me in was already in the apartment. Luckily I found a very nice person that made a few phone calls and worked it out.
