We spent almost a week in this apartment and loved it.
Tiffy was really responsive on email and answered all my questions.
Tiffy's lovely Mother met us at the apartment to give us the keys. Tiffy's Mother was also flexible with our checkout time and even spent time finding a reliable taxi for us and negotiating the fare to the airport with the driver on our behalf which was awesome.
The location is fantastic. It's in a great area, close to all of the Recoleta sights (Fuerza Abruta, the cemetery, the national art gallery, parks) restaurants, and food shops. We also walked to the Latin American Art Gallery which was a pleasant 20 minute walk away. There are several laundry places on the same street too. The Recoleta tourist information office is a 5 minute walk away and from there we got a really good map and you can ask about what there is to see etc.
The closest metro station (where you can get a train to San Telmo or Plaza de Mayo) is about a 15 minute walk away.
The main entrance of the building is on one of the busiest streets in Recoleta with a bus stop in front of it so we felt safe walking around at night. The apartment itself actually faces the back of the building and was really quiet which was perfect for us and we slept really well.
The apartment was very clean with high quality fluffy towels and nice bed linen and pillows. The bed and the couch were really comfortable and there was a large table to sit around as well as a TV with lots of English channels.
The kitchen was well stocked with salt and pepper, and enough pots and pans for us. We cooked a few meals there which was great.
The bathroom looked new and was nicely decked out with a hot powerful shower and also a bath.
There was also a small balcony which was good for some fresh air.
The building itself is a bit dated with old style lifts but we got used to using them and the people we met in the block were all friendly.
Wi-fi was available in the apartment throughout and was excellent! It was very quick and we managed to make a few Skype calls.
Would definitely recommend. Great Value.
