We had a great stay in Nuria's appartment. We arrived earlier than the check in time but Nuria was happy for us to leave our bags at the appartment until it had been cleaned. We did not meet Nuria herself but were warmly welcomed by Olga who explained everything about the appartment to us. Nuria supplied us with excellent information by email before our arrival. The appartment was very clean and had everything that we needed for our stay. There was plenty of space for the 4 of us. We were able to easily walk to the main tourist attractions and there were fantastic places to eat and drink all around. We would definitely stay again if we return to Madrid.
